Cell-permeable. A potent protein kinase C (PKC) inhibitor (IC50 = 7.9nM). In vitro, discriminates between Ca2+- dependent and -independent isoforms of PKC; selectively inhibits PKC alpha and PKC beta1 (IC50 values are 2.3 and 6.2 nM respectively) but does not inhibit the activity of PKCd, -E, or -Z (IC50 > 3microM).
Storage and Stability:
Lyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with DMSO. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
