ODN 1668
Based on 1 publication(s) in Google Scholar
ODN 1668, a class B CpG ODN (oligodeoxynucleotide), is a TLR-9 agonist. ODN 1668 has strong immune regulatory properties, can enhance the level of antibody IgG2 subtype, promote the immune response of T cells and B cells, and can be used in the study of vaccine adjuvants. In addition, CpG ODN 1668 induces an antimicrobial immune response via a CaTLR9 dependent pathway in groupers. Sequence: 5'-tccatgacgttcctgatgct-3’.

TLR9 |
ODN 1668 (6-60 µg/mL; 12-72 h) increases the synthesis of S100A8/A9, IL-6 and β-galactosidase in mouse bone marrow derived macrophages[1].
ODN 1668 (24 h) promotes the activation and proliferation of B cells and increases the expression of CD86 and CD25[2].
ODN 1668 (0.3-3.0 μM; 4 days) promotes cell growth in anti-CD3-treated CD8+ T cells in a dose-dependent manner[2].
ODN 1668 (0.25-32 μg/mL; 12 h) promotes the proliferation of head kidney lymphocytes and enhances the expression of immune genes[3].
