| Description | Truncated analog of alpha-GalCer. iNKT cell glycolipid agonist. Immunosuppressive. Th2 polarizing. Stimulation of NKT with OCH results in release of primarily Th2 cytokine compared to stimulation with alpha-GalCer, which results in release of a mixture of Th1 and Th2 cytokines. Induces stronger interleukin-4 (IL-4) secretion and weaker interferon-gamma (IFN-gamma) secretion than alpha-GalCer both in vitro and in vivo. Inducer of interleukin-10 (IL-10) and suppressor of diabetes. Shown to prevent experimental autoimmune encephalomyelitis (EAE) in mice, an animal model of multiple sclerosis. Has beneficial effects on type I diabetes in NOD mice. Suppressor of collagen-induced arthritis. Might be useful for immunotherapy of transplant rejection. CAS Number: 383187-82-4 Formula: C39H77NO9 Solubility: DMSO, 100% ethanol (warm) or methanol (warm) Method for Determining Identity: Proton NMR Molecular Weight: ~704.0 Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months after receipt at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
