A & C-Classes TLR9 Agonist Kit

Set of known multispecies TLR9 agonists (A & C-Classes CpG ODNs)

This kit contains CpG ODNs that belong to the A or C class. They are active in several species.

- ODN 1585 - A-class, mouse preferred
- ODN 2216 and ODN 2336 - A class, human preferred
- ODN 2395 and ODN M362 - C-class, human/mouse
- ODN D-SL03 - C-class multispecies


Specificity: TLR9 agonists

Quality control
- TLR9 activity has been tested using HEK-Blue™ TLR9 cells.
- The absence of bacterial contamination (e.g. lipoproteins and endotoxins) has been confirmed using HEK-Blue™ TLR2 and HEK-Blue™ TLR4 cells.

CpG ODNs are synthetic oligonucleotides that contain unmethylated CpG dinucleotides in particular sequence contexts (CpG motifs) that are recognized by Toll-like receptor 9 (TLR9) leading to strong immunostimulatory effects.

Three classes of stimulatory CpG ODNs have been identified, classes A, B and C, which differ in their immunostimulatory activities [1, 2].
Class A CpG ODNs are characterized by a phosphodiester central CpG-containing palindromic motif and a phosphorothioate 3’ poly-G string. They induce high IFN-α production from plasmacytoid dendritic cells (pDC) but are weak stimulators of TLR9-dependent NF-kB signaling.
Class C CpG ODNs contain a complete phosphorothioate backbone and a CpG-containing palindromic motif. Class C CpG ODNs are potent inducers of IFN-α from pDC and strong B cell activators [3, 4].

This kit contains CpG ODNs that belong to the A or C class. They are active in several species.

• ODN 1585 is a A-class CpG ODN with a preference towards mouse TLR9.

• ODN 2216 & ODN 2336 are A-class CpG ODN with a preference towards human and mouse TLR9.

• ODN 2395 & ODN M362 are C-class CpG ODN with a preference towards human TLR9.

• ODN D-SL03 (double-stem loop ODN) is a C-class CpG ODN and a TLR9 agonist in a diverse vertebrate species (humans, mice, rats, rabbits, pigs, swine and dogs).
