| Trans-Phosphorylation Assay |
Description: | The inhibitory activity of putative kinase inhibitors and the potency of selected compounds were determined using a trans-phosphorylation assay. Specific peptide or protein substrates were trans-phosphorylated by their specific ser-thr or tyr kinase in the presence of ATP traced with 33P-gamma-ATP, and in the presence of their own optimal buffer and cofactors.At the end of the phosphorylation reaction, more than 98% unlabeled ATP and radioactive ATP were captured by an excess of the ion exchange dowex resin; the resin then settled down to the bottom of the reaction plate by gravity. Supernatant was subsequently withdrawn and transferred into a counting plate, then evaluated by beta-counting. Kinase Buffer (KB):The buffer for PIM1 assay was composed of HEPES 50 mM, at pH 7.5, with 10 mM MgCl2, 1 mM DTT, 3 uM NaVO3, and 0.2 mg/mL BSA. Full-length human PIM1 was expressed and purified as described in Bullock A N, et al., J. Biol. Chem. 2005, 280, 41675-82. |
