Okadaic acid

SKU: orb1706881

Description

Okadaic acid is a potent marine toxin and selective protein phosphatase inhibitor that increases cellular protein phosphorylation. It is widely used in research to model diseases like Alzheimer's and cancer, both in vitro and in vivo, by inducing tau phosphorylation and acting as a tumor promoter.
