Host cell line: Sf9 cells
Specific activity: 117 pmol/min/ug
Immunogen Region
2-360
Tag
N-terminal His-tag
Formulation
40 mM Tris-HCl, pH 8.0,110 mM NaCl, 2.2 mM KCl, 0.04% Tween-20, 3 mM DTT, and 20% glycerol
Species
Human
Application
Useful for studying enzyme kinetics, screening inhibitors, and selectivity profiling.
Notes
Assay was done in Kinase buffer containing 0.2 mM DTT using P38 peptide substrate (0.1 mg/ml) and 20 mM ATP. Reaction was done at 30°C for 40 min. Amount of ATP transferred was calculated using Kinase-Glo reagent (Promega)
Storing diluted enzymeis not recommended, if necessary, usecarrier protein (BSA 0.1 - 0.5%). Avoid freeze/thaw cycles.
