Recombinant Human PTPN1 protein, Bioactivity Validated

Cat.No.: PTPN1-31256TH
Product Overview: Recombinant Human PTPN1(1-321aa) was expressed in E. coli.
Description: The protein coding region of the catalytic domain of PTP-1B (amino acids 1-321) was cloned into an E. coli expression vector. The catalytic domain of PTP-1B was overexpressed in E. coli as a soluble protein, and it was purified by conventional column chromatographic techniques.
Source: E. coli
Species: Human
Form: Liquid. 25 mM Tris-HCl, pH7.5, 2 mM beta-mercaptoethanol, 1 mM EDTA, 1 mMDTT, 20% Glycerol
Bio-activity: Specific activity is > 10,000 units/mg, and is defined as the amount of enzyme that hydrolyze 1.0 nmole of p-nitrophenyl phosphate (pNPP) per minute at pH 7.5 at 37°C.
Molecular Mass: 37.3 kDa (321 aa)
