CRISPR-Cas9

SkyangBio’s transEDIT family of CRISPR-Cas9 reagents provide researchers with the tools to make targeted edits to any gene. With our wide selection of lentiviral vectors, it is possible to perform gene editing experiments in nearly any cell type. Additionally, SkyangBio provides the reagents and custom solutions required for CRISPR activation (CRISPRa) and CRISPR interference (CRISPRi) experiments.

CRISPR-Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene editing technology that allows for precise and targeted modifications to an organism’s DNA. The CRISPR-Cas9 system is used to create a double-stranded break (DSB) in the DNA at the target DNA site specified by the gRNA. The Cas9 enzyme cleaves both strands of the DNA at the target site, which triggers the cell’s natural DNA repair machinery.

SkyangBio provides easy access to this technology through a comprehensive offering of lentiviral vector backbones and expert cloning services. One of the critical components of the CRISPR gene editing process is gRNA design. SkyangBio utilizes the CRoatan algorithm developed at Cold Spring Harbor Laboratories which selects gRNAs for optimal specificity, efficiency and target DNA accessibility. Additionally, the breadth of our available vectors provides maximum flexibility to allow for single and dual guide configurations as well as all-in-one vectors comprised of both gRNA and Cas9 expression cassettes.

SkyangBio also specializes in CRISPR-Cas9 systems that can be used for gene activation CRISPRa (dCas9-VPR) and gene interference CRISPRi (dCAS-KRAB) that do not create DNA breaks, but rather use a catalytically inactive Cas9 to target trans-activators or repressors to specific regions of a gene’s promoter.

CRISPR Cas9 and dCas9 expression vectors

SkyangBio offers Cas9 and dCas9 in a variety of lentiviral vector configurations for your CRISPR, CRISPRa and CRISPRi research.

Cas9 Vectors

SkyangBio provides Streptococcus pyogenes (SpCas9) for CRISPR gene editing. Once expressed, the nuclease binds to gRNA to form a complex which recognizes a specific genomic target sequence and induces a double-stranded break.

dCas9-VPR Vectors

dCas9-VPR fuses a tripartite complex (VPR) with nuclease-inactive Cas9 (dCas9) which is unable to perform DNA cleavage. The VPR domain consists of three transcriptional activators (Vp64, p65, and Rta) thus resulting in targeted gene activation rather than gene editing when directed (via gRNA) to a target site near a promoter region of a gene. The dCas9-VPR system offers a combination of robust and potent gene activation along with ease of use compared to other systems.

dCas9-KRAB Vectors

dCas9-KRAB fuses the transcriptional repression KRAB domain (Krüppel-associated box) to deactivated Cas9 (dCas9). When dCas9-KRAB is directed to a promoter region of a target gene via a gRNA molecule the KRAB domain recruits co-repressor proteins, which interfere with the transcriptional machinery and results in the strong repression of gene expression.

Format:

Constructs are delivered as glycerol stocks or ready-to-use viral particles.

RNA interference (RNAi)

With an extensive catalog of constitutive and inducible lentiviral vectors to choose from, SkyangBio offers complete flexibility when planning your shRNA gene knockdown experiment.

RNA interference (RNAi) is the silencing or knockdown of a gene’s expression by specific inactivation of the corresponding mRNA using double-stranded RNA (dsRNA). SkyangBio provides a comprehensive array of tools that enable highly efficient gene knockdown at the transcript level. Our advanced lentiviral based shRNA knockdown vectors utilize a uniquely optimized miR30 scaffold (UltramiR) which maximizes shRNA processing and improves the stability and specificity of the expressed shRNAs. Additionally, our systems utilize RNA polymerase II promoters that promote high expression of long RNAs which allow for multi-cistronic expression cassettes that can include shRNAs and additional reporter genes. Our shRNA designs are created using the shERWOOD algorithm which was developed with collaborators from Cold Spring Harbor Laboratory and predict shRNA’s for maximum potency and can predict rare shRNA designs that are efficient at single copy representation in the genome.

The use of lentiviral vectors to deliver and express shRNAs offers a variety of advantages including stable integration, long-term/permanent expression of the shRNA, and highly efficient and uniform vector delivery (compared to plasmid transfection). We also offer Tet-Inducible shRNA systems to allow complete control over the expression profile and temporal kinetics of shRNA expression.

SkyangBio’s shRNA designs and vectors can also be used to target long non-coding RNAs (lncRNAs) that do not encode for a gene but are involved in key cellular process such as transcriptional regulation, post-transcriptional regulation (e.g. splicing and translation), epigenetic regulation, and nucleation of protein complexes.

shRNA Target Gene Sets

shRNA target gene sets consist of 3 unique shRNA constructs plus a negative control. All constructs are 100% sequence-confirmed before shipping. SkyangBio offers an extensive catalog of shRNA lentiviral, inducible lentiviral, and retroviral vectors, allowing for complete flexibility when planning for your gene knockdown experiment.

shRNA Mouse Whole Genome Arrayed Library

shERWOOD shRNA design + Optimized shRNA processing = Superior Knockdown

SkyangBio’s shERWOOD-UltramiR™ shRNA libraries are next-generation, vector-based RNAi triggers designed using the proprietary shERWOOD algorithm that was developed and validated in Dr. Gregory Hannon’s laboratory at Cold Spring Harbor Laboratory (Knott et al 2014). The library uses an alternate microRNA scaffold called “UltramiR“. The UltramiR scaffold has been optimized for increased shRNA processing and potency based on the key determinants for primary microRNA processing (Auyeung et al 2013).

The shERWOOD algorithm is based on the functional testing of over 250,000 shRNA sequences using a high-throughput sensor assay and uses key sequence characteristics for predicting shRNA potency to select the rare shRNA designs that are potent at single copy representation in the genome.

Features

  • Over 18,000 mouse genes targeted
  • Each mouse gene is targeted by an average of 5 shRNA constructs
  • The shRNAs are cloned into a retroviral vector that contains a Neomycin selection marker and a ZsGreen fluorescent reporter

Advantages

  • The proprietary shERWOOD algorithm was used to design all shRNA. Read the publication in Molecular Cell
  • The UltramiR microRNA scaffold increases shRNA processing and potency
  • All mouse shRNA library constructs are 100% sequence-confirmed
  • Glycerol stock 96-well plates are easily maintained and offer a convenient workflow

Deliverables

SkyangBio’s shERWOOD-UltramiR™ shRNA libraries are next-generation, vector-based RNAi triggers designed using the proprietary shERWOOD algorithm that was developed and validated in Dr. Gregory Hannon’s laboratory at Cold Spring Harbor Laboratory (Knott et al 2014). The library uses an alternate microRNA scaffold called “UltramiR“. The UltramiR scaffold has been optimized for increased shRNA processing and potency based on the key determinants for primary microRNA processing (Auyeung et al 2013).

The shERWOOD algorithm is based on the functional testing of over 250,000 shRNA sequences using a high-throughput sensor assay and uses key sequence characteristics for predicting shRNA potency to select the rare shRNA designs that are potent at single copy representation in the genome.

Frequently Asked Questions

Don’t see your question? Contact Us and we will be happy to help!

How are your shRNA constructs verified?

SkyangBio used the shERWOOD algorithm to develop the whole genome library. Every shRNA construct in the library has been sequenced-verified. Each shRNA construct is not functionally validated but is designed using algorithms that were functionally validated. Please refer to the publication in Molecular Cell located in the product information at the bottom of the page.

Can I also get a backup copy of the library (glycerol stocks)?

Yes, SkyangBio can quote to provide an extra copy of each 96-well plate (glycerol stock).

Can I get purified plasmid DNA instead of, or in addition to, glycerol stocks?

Yes. SkyangBio can provide a quote for preparing 96-well plates of purified plasmid DNA. Please contact us at info@stratech.co.uk

What do I receive when I order the whole genome library?

You will receive 1,089 96-well plates containing ~300ul of bacterial glycerol stock in each well. You will also receive the datafile showing shRNA construct is in each well.

Can I just get my genes of interest cherry picked into a subset instead of buying the entire library?

Yes, send a list of your genes to info@stratech.co.uk and we will provide you with a quote and additional details.

If I purchase the whole genome arrayed library, can I share the clones with my collaborators?

Frequently Asked Questions

Don’t see your question? Contact Us and we will be happy to help!

What if I don’t find the gene I’m looking for using the search tool?

Please contact us at info@stratech.co.uk and let us know what you are looking for. It is possible we can find your gene using an alias gene symbol or different gene identifier. If we don’t have the gene, we are happy to prepare a quote for a custom gene synthesis.

How are the MGC premier cDNA and ORF clones verified?

The MGC premier cDNA and ORF clones were created by an NIH initiative that involved a consortium of laboratories. All of the cDNA and ORF clones in the library were sequenced by the consortium to confirm that each clone is full-length. The data for all of the MGC cDNA and ORF clones can be found in GenBank. The SkyangBio gene search results conveniently link each clone to GenBank for your review.

I see an “end-sequenced before shipping” option for all MGC premier cDNA and ORF clones. What is this?

SkyangBio is a distributor (and the official archive site) for the MGC libraries. When you purchase a clone from one of these libraries, we will prepare a fresh glycerol stock clone and will ship it overnight to your lab. Good laboratory practice is to sequence-confirm the clone before starting your experiment. SkyangBio offers the option to perform this for you. We will end-sequence the cDNA or ORF clone and will BLAST that sequence against the sequence for that clone in GenBank. The sequence-confirmed clone will be shipped to you along with the BLAST report showing the clone has been sequence-confirmed. Note that we do not sequence the entire insert. We sequence enough of the insert to show that you have the correct clone.

What is the difference between a cDNA and an ORF clone?

cDNA clones will contain the untranslated regions (UTRs), where the ORF (Open Reading Frame) will have the UTRs removed.

I see that some ORF clones say, ‘with stop codon’ or ‘without stop codon’. What does this mean?

The ORF clones were made by a consortium of laboratories. Some labs chose to include a stop codon in the ORF. Other labs chose to remove the stop codon in the ORF to make it easier to add a tag or linker if needed.

What do I receive when I order a cDNA or ORF clone?

You will receive a 2ml tube that contains 600ul bacterial glycerol stock.

I noticed that the caps on my tubes are different colors. Why is this?

SkyangBio uses different cap colors to indicate the bacterial antibiotic selection. Red caps need to be grown with ampicillin (or carbenicillin). Green caps need to be grown with kanamycin. Black caps need to be grown with chloramphenicol.

I need to order several cDNA or ORF clones. Can I have them delivered in 96-well plates?

Yes, SkyangBio can cherry pick your genes of interest into 96-well plates. Contact us at info@stratech.co.uk, let us know what you need and we will prepare a quote for you.

Can I get a discount if I order a lot of cDNA or ORF clones at once?

Yes, SkyangBio offers bulk discounts on cDNA and ORF clones. Just contact us at info@stratech.co.uk and let us know what you need, and we will prepare a quote for you.

Can I purchase the entire cDNA and ORF arrayed libraries?

Yes, SkyangBio can provide you with a copy of the entire arrayed libraries. Just contact us at info@stratech.co.uk and let us know what you need, and we will prepare a quote for you.

Can I receive purified plasmid DNA instead of glycerol stocks?

Yes, SkyangBio is very flexible in what we can offer. Just contact us at info@stratech.co.uk and let us know what you need, and we will prepare a quote for you.

Can I receive the cDNA or ORF constructs on blotting paper for ease of shipping overseas?

Yes, SkyangBio offers clones on Whatman blotting paper. Just contact us at info@stratech.co.uk and let us and we can provide details and a quote.

I see that you offer different clones for the gene I’m interested in. How do I know what to choose?

Please contact us info@stratech.co.uk for more information.

Are the MGC cDNA and ORF clones in expression vectors?

Not all of the cDNA and ORF clones are in an expression vector. Some of the cDNA clones are in the pCMV-SPORT6 vector which is a mammalian expression vector. Some of the ORF clones are in the pLX304 vector which is a lentiviral expression vector.

High-quality, fully-sequenced cDNA and ORF clones offered at exceptional academic prices

MGC premier cDNA and ORF arrayed libraries are genome-scale collections developed through academic and commercial collaborations using the most rigorous sequencing process, ensuring the highest quality and confidence.

MGC premier human and mouse cDNA libraries

The goal of the Mammalian Gene Collection (MGC), a trans-NIH initiative, was to provide researchers with unrestricted access to sequence-validated, full-length, protein-coding (FL-CDS) cDNA clones. SkyangBio offers the complete MGC collection – separated into human and mouse arrayed libraries. Sub-libraries containing only pCMV-SPORT6 expression-ready clones are also conveniently available.

MGC premier human ORFeome Collaboration Library

The MGC premier human ORFeome Collaboration Library currently represents 9,804 genes with 16,581 clones. The majority of the ORFeome collaboration targets were generated by the Dana Farber Cancer Institute-Center for Cancer Systems Biology (DFCI-CCSB). These full-length, annotated and sequence-verified ORFs originate from the existing collection of MGC premier full-length human cDNA clones and have been transferred into Gateway Entry vectors as a ready-to-use resource for recombinant protein expression. For additional convenience and versatility, the ORF clones are available in two formats, with and without stop codons. The ORF clones without stop codons facilitate the synthesis of either C- or N- terminal fusion proteins and clones with stop codons enable the synthesis of native proteins in addition to N-terminal fusion proteins.

The MGC premier ORFeome Collaboration Collection is also available for the mouse and represents 1,434 genes with 1,956 clones.

Frequently Asked Questions

Don’t see your question? Contact Us and we will be happy to help!

What do I receive?

You will receive a 2ml tube that contains 600ul of glycerol stock for your yeast deletion strain.

How should I grow my yeast deletion strains?

SkyangBio grows yeast deletion strains in YPD media with G418 at 30C for 24-48 hours. After incubation, we add 20% glycerol, shake, and freeze at -80C.

What background strain was used to make this collection?

The parental strain used was S288C (Haploid-Mating type alpha). The genotype was MATα SUC2 gal2 mal2 mel flo1 flo8-1 hap1 ho bio1 bio6.

How do I verify my strain considering mating types of the yeast deletion strains (haploid versus diploid)?

Strain identity can be confirmed by PCR using primers specific to the gene and the selection marker. Knockout alleles require primers specific to the knockout cassette for PCR amplification while wild type alleles are PCR amplified by gene specific primers. Haploid and homozygous deletion strains are positive for knock out allele PCR products and negative for wild type allele PCR products. Heterozygous strains should be positive for all bands. Primer sequences and expected PCR amplicon sizes are available on the clone details page for each strain. More information is available in the Yeast Deletion Product Guide.

How was the yeast deletion strain made?

Each gene was knocked out using homologous recombination and replaced with a Kanamycin cassette and uptags/downtags/barcode so the strains can be selected on G418 and identified in high throughput screening.

The Yeast Deletion Project website from the source lab at Stanford no longer exists. How do I get more information for this collection?

Yeast Deletion Collection

Genome-wide yeast collections

In 1996 S. cerevisiae became the first eukaryotic genome to be fully-sequenced, enabling the creation of the first molecular-barcoded, genome-wide yeast deletion collection (1, 2). The collection includes over 20,000 deletion strains corresponding to 5,916 genes (including 1,159 essential genes).
Each strain has a complete start-codon to stop-codon deletion of an open reading frame (ORF) that is flanked by two molecular barcodes. This collection has been used successfully in a number of screens and has been cited over 780 times (3).

Advantages

  • Molecular barcodes allow high-throughput parallel screening of entire genome
  • Complete deletions that ensure no residual gene function
  • Homozygous and heterozygous formats ready for screening
  • Haploid collections can be crossed to cell-based assay strains to expand screening options

Yeast deletions are available as individual strains, arrayed in 96-well plates, and pooled screening libraries

  • Yeast Homozygous Diploid Collection – Genome-wide screening under various conditions
  • Yeast Heterozygous Diploid Collection – Screening for haploid sufficient genetic interactions
  • Yeast MAT-a or MAT-alpha Haploid Collections – Cross to other strains expanding options for screening assays
  • Yeast Essential Collection – Targeting genes essential for growth on rich media

Pooled Screening Libraries

Pooled format is available for simultaneous analysis of large numbers of deletion strains through selective growth conditions. Identification and quantitation of the deletions surviving selection can be determined by hybridizing the deletions to a microarray containing all the barcode oligos. The barcode oligos are unique to each deletion, allowing rapid, high-throughput identification of the deletions. Each Yeast Deletion Pool contains all the deletions within the strain, equally represented within the pool. Yeast Deletion Pools are supplied in ten tubes, each containing 500 µl of the pooled deletions.

Yeast Deletion Collections

The Yeast Deletion Collections were created by systematically targeting every open reading frame (ORF) and creating a start- to stop-codon deletion. The cassette used to delete the ORF consists of a selectable marker (kanamycin-resistance KanMX4) flanked by two barcode sequences. These are referred to as the UPTAG and DOWNTAG and are unique to each gene. The 5′ and 3′ sequences of the cassette are homologous to the targeted gene to allow recombination. Following recombination, the selection marker replaces the ORF and the barcodes are integrated into the genome.

High Throughput Parallel Screening

The UPTAG and DOWNTAG barcodes (Figure 1) allow high-throughput parallel screening. Starting with a population where each yeast deletion strain is represented equally, selective pressure can be applied. Strains resistant to the selection become more highly represented than sensitive strains during growth of the culture. The changes in population correlate with changes in the barcode representation and can be analyzed by microarray or next generation sequencing.

The selective pressure is determined by the type of screen. One of the initial validations of the yeast knockout collection highlights its utility and flexibility by performing a number of screens using selection for growth in high salinity, low salinity, high pH, changes in carbon source and peroxide stress1. There have been a number of screens since including, but not limited to, examining exposure to ionizing radiation, DNA damaging reagents and defects in cell division2.

What do I receive?

For arrays, you will receive 96-well plates containing around 200ul of culture in YPD+G418+glycerol. Each plate is clearly labeled to match the datafile.

How should I grow my yeast deletion strains?

SkyangBio grows yeast deletion strains in YPD media with G418 at 30C for 24-48 hours. After incubation, we add 20% glycerol, shake, and freeze at -80C.

How do you ensure the yeast deletion pools contain equal representation of deletion strains?

SkyangBio follows a common pooling process where we stamp all 96-well plates containing the deletion strains onto YPD agar+G418. We allow all deletion strains to grow to a uniform colony size and then we add YPD media to each agar plate and gently scrape the colonies into one flask. The pool of deletion strains is then mixed well and dispensed into individual vials. This is a standard protocol that has been used by the yeast community over the past several years. No further QC is applied to the pools.

Lentiviral Cloning Vectors

SkyangBio offers a large selection of lentiviral cloning vectors for CRISPR, shRNA and Gene Expression applications.  A menu of promoters, selectable markers and fluorescent reporters allows you to customize your vector for your specific application.

All SkyangBio lentiviral vectors are 3rd generation transfer plasmids and have been optimized for efficient 3rd generation lentiviral packaging. The use of a 3rd generation packaging system significantly reduces the likelihood of generating replication-competent lentivirus and thus results in improved safety over earlier packaging systems. This is accomplished by introducing several key changes:

  • Dependence of Tat transactivation is eliminated by the use of a chimeric 5′ LTR fused to a heterologous promoter on the transfer plasmid.
  • 4 plasmids are required for generating virus because the packaging system is split into two plasmids to separate Rev from Gag and Pol
  • All expression vectors have been made self-inactivating (SIN) via a deletion in 3′ LTR (ΔU3). This deletion is transferred into the 5’LTR after one round of reverse transcription and abolishes transcription of the full-length virus after it has incorporated into a host cell.

Note that a 3rd generation transfer plasmid can be used with a 2nd generation packaging system, but a 2nd generation transfer plasmid cannot be used with a 3rd generation packaging system.

Cloning vectors are typically shipped the day of order.

Biosafety should always be considered, and your biosafety office can provide more information on your institution’s best practices with regard to lentiviral research.

NOTE: Our cloning vectors are to be used for Research Use Only.

CRISPR-Cas9 Cloning Vectors

Our CRISPR-Cas9 cloning vectors are ideally suited for cloning gRNAs by following the simple cloning steps outlined in the cloning guidelines (see below). A menu of promoters, selectable markers and fluorescent reporters allows you to customize your vector for your specific application.

Advantages:
All SkyangBio lentiviral vectors are 3rd generation transfer plasmids and have been optimized for efficient 3rd generation lentiviral packaging. The use of a 3rd generation packaging system significantly reduces the likelihood of generating replication-competent lentivirus and thus results in improved safety over earlier packaging systems. This is accomplished by introducing several key changes:

Dependence of Tat transactivation is eliminated using a chimeric 5′ LTR fused to a heterologous promoter on the transfer plasmid.

4 plasmids are required for generating virus because the packaging system is split into two plasmids to separate Rev from Gag and Pol

All expression vectors have been made self-inactivating (SIN) via a deletion in 3′ LTR (ΔU3). This deletion is transferred into the 5’LTR after one round of reverse transcription and abolishes transcription of the full-length virus after it has incorporated into a host cell.

Format:

Constructs are delivered as glycerol stocks.
