Okadaic Acid, a marine toxin, polyether derivative produced by dinoflagellates, is a potent, cell-permeable, specific inhibitor of PP-1 and PP-2 serine/threonine-speci c protein phosphatases in a variety of cell types. Salt form of okadaic acid, with somewhat greater stability than the free acid when stored in organic solvents. Source: Prorocentrum concavum Solubility: Soluble in DMSO or ethanol. Storage and Stability: Light Sensitive. Store at -20°C. Stable as a powder for at least 12 months. Stable as a liquid for 6 months. WARNING: Highly irritant to skin and mucous membranes. SPECIAL HAZARD: TUMOR PROMOTER. Gloves and mask should be worn when using this compound. Care must be taken to prevent contact through all routes of exposure. CAS Number: 209266-80-8 Molecular Formula: C44H68O13•Na Molecular Weight: 826.98 |
Source: Prorocentrum concavum Purity: Purified by preparative flash, medium pressure nad high performance liquid chromatography. Form: Supplied as white powder.
