Figure 1. PKCalpha kinase activity was measured in a radiometric assay using the following reaction conditions: 60 mM HEPES-NaOH, pH 7.5, 3 mM MgCl2, 3 mM MnCl2, 3 µM Na-orthovanadate, 1.2 mM DTT, 1 µM ATP, 2.5 µg/50 µl PEG20,000, Substrate: Histone H1, 5 µg/50 µl and Recombinant PKCalpha: 25 ng/50 µl.
Figure 3. Dose dependence curve of PKCalpha kinase activity: DELFIA® data generated using Phospho-PKA Substrate (RRXS/T) (100G7) Rabbit mAb #9624 to detect phosphorylation of substrate peptide (#1331) by PKCalpha kinase. In a 50 µl reaction, increasing amounts of PKCalpha and 1.5 µM substrate peptide were used per reaction at room temperature for 15 minutes. (DELFIA® is a registered trademark of PerkinElmer, Inc.)

Staurosporine inhibition of PKCalpha kinase activity: DELFIA® data generated using Phospho-PKA Substrate (RRXS/T) (100G7) Rabbit mAb #9624 to detect phosphorylation of PKCalpha substrate peptide (#1331) by PKCalpha kinase. In a 50 µl reaction, 10 ng PKCalpha, 1.5 µM substrate peptide, 20 µM ATP and increasing amounts of staurosporine were used per reaction at room temperature for 15 minutes.
