Applications: Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Assay Conditions: A 50 µl Galactokinase reaction isconducted in a buffer containing 20 mMTris (pH 7.4), 5 mM MgCl2, 50 mM NaCl,50 µM ATP, 1 mM DTT and 1 mMsubstrate D-Galactose at roomtemperature for 1h. ATP reduction isdetected using Kinase-Glo® LuminescentKinase Assay Platform.
