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’.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (ODN 1668 sodium) that retains the same biological activity.

In Vitro

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].

Real Time qPCR[3]

Cell Line: Head kidney lymphocytes
Concentration: 2 μg/mL
Incubation Time: 12 h
Result: Increased the mRNA levels of TLR9, IL-1β, IL-6, IL-8, TNF-α, IFN-γ, MHC-Iα and MHC-IIα.
In Vivo

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
