PKCmu (PKD1) Human CAMK Kinase Enzymatic Radiometric LeadHunter Assay [10 μM ATP] - TW

Procedure Summary:

Human recombinant protein kinase PKCm expressed in Sf158 insect cells is used. Test compound and/or vehicle is preincubated with 1 μg/ml enzyme‡, 1.5 mM Ca2+, 50 μg/ml phosphatidylserine and 8 μg/ml diacylglycerol modified HEPES buffer pH 7.4 for 15 minutes at 37⁰C. The reaction is initiated by addition of 250 μg/ml histone H1, 10 μM ATP and 0.25 μCi [γ32P]ATP for another 30 minute incubation period and terminated by further addition of 3% H3PO4. An aliquot is removed and counted to determine the amount of [32P]Histone H1 formed. Compounds are screened at 10 μM.
