Application

Useful for the study of enzyme kinetics, regulation, to dephosphorylate target substrates and for screening inhibitors.

General description

Catalytic domain, (amino acids 817-1188), (Gene bank accession number NM_005401) with N-terminal GST tag, MW = 61 kDa, expressed in an E. coli expression system.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 75 mM NaCl, 0.05% Tween-20, 50% glycerol, 2 mM EDTA, 1 mM DTT, and 10 mM glutathione.

Preparation Note

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

Unit Definition

One unit will hydrolyze 1 nmol p-nitrophenyl phosphate per minute at pH 7.4 and 30°C.
