General description

A convenient set that offers several highly selective serine/threonine kinase inhibitors. Kinases play an important role in numerous signaling cascades. Highly selective protein kinase inhibitors are useful for dissecting these cascades to determine which specific kinases are involved in producing particular biological effects. The Serine/Threonine Kinase Inhibitor Set contains the following highly selective serine/ threonine kinase inhibitors in one convenient set:

• Bisindolylmaleimide I (Cat. No. 203290), 250 µg

• H-89, Dihydrochloride (Cat. No. 371963), 1 mg

• KN-93 (Cat. No. 422708), 1 mg

• ML-7 (Cat. No. 475880), 1 mg

• Protein Kinase G Inhibitor (Cat. No. 370654), 1 mg

• Staurosporine (Cat. No. 569397), 100 µg
