产品说明
一般描述
Protein tyrosine phosphatase, Catalytic domain, (amino acids 2-315), (Gene bank accession number BC016727) with N-terminal GST tag, MW = 62.3 kDa, expressed in an E. coli expression system.
应用
Useful for the study of enzyme kinetics, regulation, to dephosphorylate target substrates and for screening inhibitors.
单位定义
One unit will hydrolyze 1 nmol p-nitrophenyl phosphate per minute at pH 7.4 and 30℃.
外形
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.
制备说明
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℃. Note: Enzyme is very sensitive to freeze/thaw cycles.
