Kinase activity is determined in an assay volume of 40 μL in kinase buffer (50 mM Tris-HCl, pH 7.5, 0.1 mM EGTA, 1 mM 2-mercaptoethanol) containing 200 ng of pure active ERK5 and the indicated amount of inhibitor. Reaction started by adding 10 mM magnesium acetate, and 50 μM [γ-³²P]-ATP (500 cpm/pmol) and 250 μM PIMtide (ARKKRRHPSGPPTA) as substrates. Assays are carried out for 20 min at 30°C, terminated by applying the reaction mixture onto p81 paper and the incorporated radioactivity measured^[1].
