| Mer Kinase Assay |
Description: | Human Mer (residues R557-E882 with H628Q and R794A, 0.7 nM) was incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 30 mM NaCl, 250 μM GGMEDIYFEFMGGKKK (SEO ID NO. 44). 10 mM magnesium acetate, and 10 μM [γ-33P-ATP]. The reaction was initiated by the addition of the Mg/ATP mix. After incubation for 40 minutes at room temperature, the reaction was stopped by the addition of phosphoric acid to a concentration of 0.5%. A reaction aliquot of 10 μL was then spotted onto a P30 filtermat and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting. Incorporated 33P was measured using the Wallac Microbeta scintillation counter (Perkin Elmer). |
