PD 98059 ≥95% (by HPLC)

PD-98059 is a potent and selective inhibitor of MAP kinase kinase (MEK). It selectively blocks the activation of MEK thereby inhibiting the phosphorylation and the activation of MAP kinase. PD-98059 is cell permeable. In PC12 pheochromocytoma cells, it completely blocked the increase in MAP kinase activity produced by NGF, IC50=2µM. Enhances self-renewal of embryonic stem cells PD-98059 is an invaluable tool to help elucidate the role of the MAPK cascade in a variety of biological systems. Inhibits cell growth and proliferation in acute myelogenous leukemia cell lines by causing cell arrest.
