Fig-2: Abeomics' CpG ODNs did not show any TLR2 agonist activity. TLR2/NF-kB Leeporter™ HEK293 cells (14-127ACL) were treated with various CpG ODNs at 100 µg/ml as well as a positive TLR2 agonist, Pam3CSK4, at 10 ng/ml for 16 h, and luciferase activity was then analyzed.

Fig-3: Abeomics' CpG ODNs did not show any TLR4 agonist activity. TLR4/IL-8 Leeporter™ HeLa cells (14-124ACL) were treated with various CpG ODNs at 100 µg/ml as well as a positive TLR4 agonist, LPS, at 10 ng/ml for 16 h, and luciferase activity was then analyzed.

Description
Description: Sequence: 5'-tccatgaCGttcctgatgct-3' (Class B ODN 1668: Bases are phosphorothioate.) Synthetic oligodeoxynucleotides (ODN) containing unmethylated deoxycytosine-deoxyguanosine (CpG) motif are equivalent to bacterial DNA in the immunostimulatory activity, which can induce innate immunity via Toll-like receptor 9 (TLR9) in mammals. There are three major classes of CpG ODNs, and each ODN class exhibits different stimulatory effects on immune cell activation. Class A ODNs are potent inducers of IFN-alpha that leads to the plasmacytoid dendritc cell (pDC) maturation. Class B ODNs are relatively weak inducers of type I IFNs but strong stimulators of human B cells and monocyte maturation. Class C ODNs combine elements of both Classes A and B ODNs, which can induce IFN-alpha in pDC and activation of B cells.

Application Notes
A. CpG ODN 1668-mediated mouse TLR9 activation in NF-kB Leeporter™- RAW 264.7 cells (Figure 2). 1. Harvest NF-kB Leeporter™- RAW 264.7 cells and seed cells into a white solid-bottom 96-well microplate in 100 µl of growth medium at 5 x 104 cells/well. 2. Incubate cells at 37°C in a CO2 incubator for overnight. 3. The next day, stimulate cells with various amounts of CpG ODN 1668. 4. Incubate at 37°C in a CO2 incubator for 6-16 hours. 5. Add 30-50 µl of luciferase assay reagent per well. 6. Incubate at room temperature for 1-5 minutes and measure luminescence using a microplate luminometer.
Storage Note
