Details

CpG ODNs are synthetic oligonucleotides that contain unmethylated CpG dinucleotides in particular sequence contexts (CpG motifs). These CpG motifs are present at a 20-fold greater frequency in bacterial DNA compared to mammalian DNA [1, 2]. CpG ODNs are recognized by Toll-like receptor 9 (TLR9) leading to strong immunostimulatory effects.

ODN 1585 is a class A CpG ODN with a preference towards mouse TLR9. Class A CpG ODNs are characterized by a phosphodiester central CpG-containing palindromic motif and a phosphorothioate 3’ poly-G string. They induce high interferon-α (IFN-α) production from plasmacytoid dendritic cells (pDC) but are weak stimulators of TLR9-dependent NF-κB signaling.

ODN 1585 Control contains GpC dinucleotides instead of CpGs and can be used as a negative control together with ODN 1585.

ODN 1826 is a class B CpG ODN with a preference towards mouse TLR9. Class B CpG ODNs contain a full phosphorothioate backbone with one or more CpG dinucleotides. They strongly activate B cells but weakly stimulate IFN-α secretion.

ODN 1826 Control (also known as ODN 2138) contains GpC dinucleotides instead of CpGs and can be used as a negative control together with ODN 1826.

ODN 2395 is a class C CpG ODN for human and mouse TLR9. Class C CpG ODNs combine features of both classes A and B. They contain a complete phosphorothioate backbone and a CpG-containing palindromic motif. Class C CpG ODNs induce strong IFN-α production from pDC and B cell stimulation.

ODN 2395 Control contains GpC dinucleotides instead of CpGs and can be used as a negative control with ODN 2395.
