Type: Binding

Description: Biochemical Assay: 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 are trans-phosphorylated by their specific serine-threonine or tyrosine 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% cold ATP and radioactive ATP is captured by an excess of the ion exchange dowex resin; the resin then settles down to the bottom of the reaction plate by gravity.Supernatant, containing the phosphorylated substrate, is subsequently withdrawn and transferred into a counting plate, then evaluated by beta-counting.Reagents/Assay Conditions i. Dowex Resin Preparation500 g of wet resin (SIGMA, custom prepared resin DOWEX 1x8 200-400 mesh, 2.5 Kg) are weighed out and diluted to 2 L in 150 mM sodium formate, pH 3.00.The resin is allowed to settle down.
