Chemical Properties

Formula Weight
Storage & Sensitivity
Store at -20°C.
It is soluble in ethanol (25 mg/ml), DMSO (25 mg/ml), methanol (<1 mg/ml), chloroform, acetone, ethyl acetate, DMF, and dimethylsulfoxide. Insoluble in water, unless first dissolved in organic solvents, such as DMSO or ethanol.


Okadaic acid, is used as an activator of PKC and inhibitor of PP1 and PP2A phosphatases. The hydrophobic backbone of okadaic acid enables it to enter cells where it stimulates intracellular protein phosphorylation. It mimics the effects of insulin, enhances transmitter release at neuromuscular junctions, causes vasodilation and is a very potent tumor promoter. Okadaic acid is an extremely useful tool for studying cellular processes that are regulated by phosphorylation. It is shown to activate atypical protein kinase C in adipocytes.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Recommended storage temperature: -20°C. Keep away fom strong oxidizing agents.
