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: Assay was done in Kinase buffer containing 20 µM Sphingosine and 20 µM ATP. Reaction was done at 30°C for 35 min. Amount of ATP transferred was calculated using Assay was done in Kinase buffer (40 mM Tris, pH 7.4, 20 mM MgCl2+, 0.1 mg/ml BSA) containing 20 µM Sphingosine and 20 µM ATP. Reaction was done at 30°C for 35 min. Amount of ATP transferred was calculated using Kinase-Glo reagent (Promega)
