Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: full length
Applications: Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Assay Conditions: A 25 µl kinase reaction is conducted in a buffer containing 40 mM Tris-HCl (pH 7.4), 20 mM MgCl2, 100 uM ATP, 200 µM PI:PS substrate (BPS catalog #40560) and p110δ/p85α enzyme for 15 minutes at 30°C. ATP reduction is detected using ADP-Glo™ Kinase Assay Platform (Promega Corporation, Madison, WI).
