Okadaic Acid, Potassium Salt has been used as a response modifier in the study of large granular lymphocyte and T-cell biochemistry. In addition to inhibitive activities it is a tumor promoter and has been used to study nitric oxide metabolism, apoptosis, cell cycle and calcium signaling. It is also used as a PP1/PP2A/PP2B/PP2C inhibitor, used to study tumor promotion/NO metabolism/apoptosis
