ODN 1585 VacciGrade™

CpG ODN 1585 is a synthetic immunostimulatory oligonucleotide (ODN) that contains unmethylated CpG dinucleotides.

ODN 1585 is a class A CpG ODN specific for mouse Toll-like receptor 9 (TLR9). In plasmacytoid dendritic cells (pDCs) it induces high IFN-α production but is a weak stimulator of TLR9-dependent NF-κB signaling (IL-6). It generates Th1-dominant immune responses.

ODN 1585 VacciGrade™ is prepared under strict aseptic conditions. It is guaranteed sterile and thoroughly tested to confirm the absence of endotoxins. ODN 1585 VacciGrade™ is suitable for preclinical studies

ODN 1585 VacciGrade™ is for research use only; it is not for use in humans.

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

Three types of stimulatory CpG ODNs have been identified, types A, B and C, which differ in their immune-stimulatory activities [3-4]. Type 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-κB signaling. Type B CpG ODNs contain a full phosphorothioate backbone with one or more CpG dinucleotides. They strongly activate B cells but stimulate weakly IFN-α secretion. Type C CpG ODNs combine features of both types A and B. They contain a complete phosphorothioate backbone and a CpG-containing palindromic motif. Type C CpG ODNs induce strong IFN-α production from pDC and B cell stimulation.

ODN 1585 is a CpG ODN type A specific for mouse TLR9 [5].
