Highly potent, cell-permeable inhibitor of protein kinases such as PKA, PKC, PKG (IC50 = 18-25 nM), Serine/threonine protein kinases (IC50 values are 10-20 nM) and CAM kinase II (Ki = 1.8 nM). Analog of staurosporine (ab120056), exhibits a wide range of effects including neuroprotection and improvement of psoriasis in vivo.
Store at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Soluble in DMSO to 25 mM and in ethanol to 5 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
