Active Recombinant Human PTPN1 protein, Bioactivity Validated

• Cat.No.: PTPN1-31256TH
• Product Overview: Recombinant Human PTPN1(1-321aa) was expressed in E. coli.

Specification

• 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.
