Okadaic acid, 98%, Thermo Scientific Chemicals
Description
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.
