Ebba Biotech AB was founded in 2016 by professor Agneta Richter-Dahlfors to enable commercial applications and more widespread use of fluorescent tracer (optotracers) molecules, the result of many years of cutting-edge nanoscience and organic chemistry research.


About our Technology

Optotracing is an innovative visualization method developed by scientists for scientists for use in fluorescence microscopy and spectroscopy. With optotracing – using fluorescent tracer molecules – Ebba Biotech provides an innovative method for several expanding areas of research. The optotracing technology has been developed by a scientific expert team of researchers at Karolinska Institutet, Linköping University and the Royal Institute of Technology (KTH) in Sweden and is a result of many years of cutting-edge nanoscience and organic chemistry research.

Ebba Biotech has commercialized distribution and sales of optotracer molecules and today supply these in three different series:

  • EbbaBiolight – to probe and detect bacteria & biofilm.
  • Carbotrace – for anatomical mapping of plants to understand their composition.
  • Amytracker – to search and detect amyloids and other protein aggregates.

Fluorescent tracers for amyloids and other protein aggregates
Amytracker are fluorescent tracer molecules providing high quality visualization of protein aggregates. Using Amytracker, pre-fibrillar states of amyloids from a variety of amyloidogenic proteins or peptides are detected in tissues and living cells.

Optotracers for carbohydrate analysis and anatomical mapping
Carbotrace are fluorescent tracer molecules targeting carbohydrate structures. Carbotrace can be used for non-destructive carbohydrate analysis, carbohydrate discrimination and anatomical mapping of carbohydrate structures in plants.

Optotracers for detection of bacteria and bacterial biofilm
EbbaBiolight are fluorescent tracer molecules allowing to identify components of bacteria and bacterial extracellular matrix. Using EbbaBiolight, it is now possible to track biofilm formation in living, growing cultures in liquid and on surfaces.

Amytracker

Amytracker are fluorescent tracer molecules for high-quality visualization of protein aggregates.

The molecules become vividly colorful – highly fluorescent – when bound to a target in a sample. Targets are amyloids or protein aggregates containing amyloid fibrils and proto-fibrils. Therefore, using Amytracker, you can achieve reliable fluorescent staining of early, pre-fibrillar states of amyloids arising from a variety of amyloidogenic proteins or peptides in tissues from a wide range of species and perform fibrillation assays and spectrophotometric detection of protein aggregates in liquid samples.

Amytracker molecules are non-toxic and are readily taken-up when applied to cells in culture. Further, they are photo- and thermostable and allow for easy handling in any application. Our ex vivo products will simplify your life when performing staining of tissue sections, live-cell imaging or fibrillation assays. The ex vivo products are available in aliquots of 50 µl, 100 µl, 150 µl or 200 µl (all delivered in 50 µl vials). Please, contact us to find out more about Amytracker for in vivo use.

Carbotrace

Carbotrace are optotracer molecules providing means for anatomical mapping of carbohydrate structures in plants and for non-destructive composition analysis of polysaccharides in bio-based materials and biofuels.

The optotracing technology has been developed by a team of researchers at Karolinska Institutet (KI), Royal Institute of Technology (KTH) and Linköping University in Sweden and is a result of many years of cutting-edge nanoscience and organic chemistry research. Optotracing has been defined by the researchers as the use of structure-responsive fluorescent molecules which become highly fluorescent when binding and exhibit unique spectral signatures dependent on the structure of their binding partner. The unique combination of fluorescence and the target-specific signal can be used to clearly identify biomolecules in various types of materials.

Carbotrace optotracers are designed for anatomical mapping of carbohydrate structures in plants and for non-destructive composition analysis of polysaccharides in bio-based materials and biofuels. The structure-responsive optotracer Carbotrace differentiates between different types of glycosidic linkages in carbohydrates. The products are available in aliquots of 50 µl, 100 µl, 150 µl or 200 µl (all delivered in 50 µl vials).

EbbaBiolight 680 is available as a 1 mg/ml solution in volumes ranging from 10 – 200 µL (see volumes and prices in the list below). AAs our standard solvent, we use ultrapure water (MilliQ). We also provide EbbaBiolight 680 dissolved in DMSO Please contact us for custom options.

EbbaBiolight Mix&Try Kit is our recommended option for starting out with using EbbaBiolight. It contains a sample volume (10 µL) of each variant. Testing each variant in the EbbaBiolight Mix&Try Kit will allow you to determine which one of our optotracers is best suited for your experiment.

All EbbaBiolight variants label extracellular and intracellular bacterial amyloids as well as certain glucans produced as part of the extracellular matrix. Specifically, the optotracers have been used as follows: EbbaBiolight 480 labeling extracellular matrix produced by P. aeruginosa but not C. albicans in a mircofluidic device during mono- and co-culture. EbbaBiolight 630 labeling peptidoglycan and lipoteichoic acids in the cell wall of certain gram positives like Staphylococci and E. faecalisEbbaBiolight 680 labeling curli in the extracellular matrix produced by Salmonella as well as β-glucans, chitin and intracellular amyloid aggregates in yeast- and hypal forms of C. albicans. Furthermore, it has been used to track pellicle biofilm formation in B. cenocepacia. Contact us to learn more about EbbaBiolight applications.

All EbbaBiolight variants are exceptionally photostable and fluorogenic. When bound to a target, the optotracers can be imaged using fluorescence microscopy and spectral information can be acquired using a fluorescence spectrophotometer. As spectral information can give hints of the nature of the target, we recommend to acquire excitation and emission spectra whenever possible. Excitation and emission wavelengths for each molecule are shown in Table 1. EbbaBiolight are intended for use in live-cultures and are not compatible with fixation. If fixation needs to be performed, we recommend to apply fixation after labelling.

Optotracer Science

Our Optotracers: EbbaBiolight, Carbotrace and Amytracker

Optotracing is an innovative visualization method developed by scientists for scientists ideal to use in fluorescence microscopy. With optotracing – using fluorescent tracer molecules – Ebba Biotech provides an innovative method for several expanding areas of research. The optotracing technology has been developed by a scientific expert team of researchers at Karolinska Institutet, Linköping University and the Royal Institute of Technology (KTH) in Sweden and is a result of many years of cutting-edge nanoscience and organic chemistry research.

Ebba Biotech has commercialized distribution and sales of fluorescent tracer molecules and today supply these in three different series:

Optotracers for labeling amyloids and other protein aggregates

Optotracers for carbohydrate analysis and anatomical mapping

Optotracers for detection of bacteria and bacterial biofilm

Video clips about Optotracing

On the first of June 2021, Ferdinand Choong, Ebba Biotech’s co-founder, and Assistant Professor at Karolinska Institutet and AIMES (Center for the Advancement of Integrated Medical and Engineering), presented his research using Ebba Biotech’s optotracers at the digital event Lab & Diagnostics of the Future 2021, held by Life Science Sweden. At this event, Ferdinand spoke about Ebba Biotech’s optotracers multifunctional tracer for disease research and diagnostics. He explains the technical concept in large and Ebba Biotech’s three product series.

The video clip about optotracing illustrates why our current model of Take, Make, Dispose is draining our planet of natural resources and why circular economy and renewable resources are the answer. Learn how Optotracers can be used to identify renewable resources in plant biomass and support circular economy in the food & beverage, pharmaceutical and chemical industry.

In the first episode of our webinar series about EbbaBiolight, Dr. Karen Butina present her research findings using optotracers for detection and quantification of Staphylococci. You can read more about Dr. Butina’s work here. DISCLAIMER: Dr. Butina describes her work using HS-167 molecules. These are predecessor molecules to what is now commercialised under the product family name EbbaBiolight, which are marketed and sold by Ebba Biotech.
