Biological Activity

Okadaic acid is a potent inhibitor of protein phosphatase 1/2A with IC50 values of 19 nM and 0.2 nM for protein phosphatase 1 and protein phosphatase 2A, respectively. Okadaic acid (100 nM) significantly induced cell apoptosis in confluent rabbit lens epithelial cells (RLECs). Okadaic acid also induced the expression of p53 and bax, which are necessary for the apoptotic programs. In N/N1003A cells, okadaic acid (10 nM) decreased total phosphatase activity by 20% and mainly inhibited PP-2A activity, while okadaic acid (100 nM) reduced 81% total phosphatase activity and inhibited PP-1 and PP-2A activity.

Protocol (for reference only)
Cell Experiment
Cell lines Clone 9 rat hepatocytes
Preparation method Cells (40000 per well) were seeded on to 96-well plates. After 24 h, OA, MeOk, MC-LR or vehicle were added to the cells. Then, a 1:10 dilution of Alamar Blue was added. Fluorescence was measured by using a microplate fluorescence reader FL600 after 24 h of incubation with the toxins.
