General description
Protein tyrosine phosphatase, Catalytic domain, (amino acids 285-593) (Gene bank accession number M83738) with N-terminal GST tag, MW = 60.3 kDa, expressed in an E. coli expression system.
Application
Useful for the study of enzyme kinetics, regulation, to dephosphorylate target substrates and for screening inhibitors.
Physical form
Formulated in 25 mM Tris-HCl, pH 8.0, 75 mM NaCl, 0.01% KCl, 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.
Other Notes
One unit will hydrolyze 1 nmol p-nitrophenyl phosphate per minute at pH 7.4 and 30°C.
