激酶实验
CDK activity assays: CDK assays for IC50 determinations and kinetic evaluation are performed in 96-well filter plates. All CDK-cyclin kinase complexes are expressed in insect cells through baculovirus infection and purified. The substrate for the assays is a fragment (amino acids 792–928) of pRb fused to GST (GST?RB-Cterm). The total reaction volume is 0.1 mL containing a final concentration of 20 mM Tris-HCl, pH 7.4, 50 mM NaCl, 1 mM dithiothreitol, 10 mM MgCl2 25 μM ATP (for CDK4-cyclin D1, CDK6-cyclin D2, and CDK6-cyclin D3) containing 0.25 μCi of [γ-32P]ATP, 20 ng of enzyme, 1 μg of GST?RB-Cterm, and appropriate dilutions of inhibitor. All components except the [γ-32P]ATP are added to the wells, and placed on a plate mixer for 2 min. The reaction is started by adding the [γ-32P]ATP, and incubated at 25℃ for 15 min. The reaction is terminated by addition of 0.1 mL of 20% trichloroacetic acid, and the plate is kept at 4?℃ for at least 1 hr to allow the substrate to precipitate. The wells are then washed five times with 0.2 mL of 10% trichloroacetic acid, and radioactive incorporation is determined with a β plate counter.
