Okadaic acid, Sodium Salt (CAT: I012067) is a modified form of Okadaic acid, which is a potent inhibitor of protein phosphatases. As the sodium salt form, it exhibits improved stability when stored in organic solvents compared to the free acid form. Okadaic acid and its derivatives are widely used in research to study cellular signaling pathways involving protein phosphorylation and dephosphorylation. By inhibiting protein phosphatases, Okadaic acid can perturb cellular processes regulated by phosphorylation, providing valuable insights into the functions of specific protein kinases and phosphatases.
