BTK(P190K), His-Tag Recombinant

Products from BPS Bioscience require a minimum order value above 400€

Encompassing Amino Acids: 2-658(end)

Applications: Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. 

Assay Conditions: Kinase activity was measured using a Poly-Glu/Tyr(4:1) substrate. Increasing amounts of the protein kinase were mixed with 0.25 mg/ml substrate in 20 µl final volume. The blank was determined from a "no substrate" sample. The reaction was initiated by addition of 5 µl of [33P]-ATP buffer containing 10 mM ATP, 1 m Ci [33P]-ATP, 25 mM MOPS, 12.5 mM β-glycero-phosphate, 25 mM MgCl2, 2 mN EDTA, 0.25 mM fresh DTT, pH 7.2. After incubating for 30°C for 15 minutes, the reaction was terminated by spotting 20 µl of the mixture onto phosphocellulose paper strips that were fixed in 1% phosphoric acid. Radioactivity was determined using a scintillation counter.
