ODN 1668 sodium
Based on 1 publication(s) in Google Scholar
ODN 1668 sodium, a class B CpG ODN (oligodeoxynucleotide), is a TLR-9 agonist. ODN 1668 sodium 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 sodium induces an antimicrobial immune response via a CaTLR9 dependent pathway in groupers. Sequence: 5'-tccatgacgttcctgatgct-3’.

Non-salt dose:
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].

Result:Increased the mRNA levels of TLR9, IL-1β, IL-6, IL-8, TNF-α, IFN-γ, MHC-Iα and MHC-IIα.
ODN 1668 (10 nmol ≈ 63.6 μg; injection into the hind footpads; single dose) significantly enhances antibody response in OVA treated mice and increases titers of IgG2a and IgG2b[2].
ODN 1668 (15 μg; intramuscular injection; single dose) improves the antibacterial immunity of Epinephelus laminatus infection, and has the most significant antibacterial activity in liver, spleen and kidney[3].
ODN 1668 (1-5 mg/kg; intraperitoneal/subcutaneous injection; single dose) can cause fever, anorexia and brain inflammation in rats[4].
