ODN 21798

ODN 21798

Oligodeoxyribonucleotides containing CpG motifs (CpG ODNs) are widely used for activation of immune cells, such as human PBMCs, murine splenocytes or isolated immune cells, e.g., B cells and pDCs. They also activate signalling in TLR9-expressing recombinant cell lines.
ODN 21798 is a P-class ODN for the activation of B cells and pDCs. Compared to C-class ODNs, P-class ODNs have a higher efficiency.

Background information

TLR9 is a prominent member of the toll-like-receptor (TLR) family recognizing pathogen-associated molecular patterns. TLR9 recognizes specifically unmethylated CpG motifs in bacterial DNA leading to activation of immune cells

. These effects can be mimicked by short synthetical oligodeoxyribonucleotides (ODNs) containing unmethylated CpG motifs

.
Several classes of CpG ODN have been identified and can be distinguished by their effects on certain cell types. A-class ODNs containing 5’ and 3’ G-rich stretches induce high levels of type I IFN but show low activation of B cell proliferation. B-class ODNs activate B cells and TLR9-dependent NFkB signalling in recombinant cell lines but show low induction of IFN-α. C-class ODN induce high amounts of IFN-α and activate B cells. The recently discovered new P-Class ODNs show similar but superior properties to C-class ODNs.

Applications

P-class ODN for activation of B cells and pDCs with higher efficiency compared to C-class ODN.
P-class ODN can form multimeric structures.
