Assay Method Information

Assay Name:  Enzymatic Activity Assay
Description:  Reaction biology kinase hotspot service (http://www.reactionbiology.com) was used to measure IC50. In a final reaction volume of 25 μL, kinase (5 mU to 10 mU) was incubated with 25 mM Tris (pH 7.5), 0.02 mM EGTA, 0.66 mg/ml of myelin basic protein, 10 mM magnesium acetate, and [33P-ATP] (specific activity of about 500 CPM/pmol, concentration as required). The reaction was initiated by addition of Mg-ATP mix. After incubation for 40 min at room temperature, the reaction was stopped by addition of 5 μl of a 3% phosphoric acid solution. 10 μL of the reaction was then spotted onto a P30 filtermat and washed three times for 5 minutes in 75 mM phosphoric acid and once in methanol prior to drying and scintillation counting.
