HRP-1194 Recombinant Human SERPINI2 Protein $150

Recombinant Human SERPINI2 Protein

Product Name: Recombinant Human SERPINI2 Protein
Catalog #:  HRP-1194
Manufacture:  LD Biopharma, Inc.

Human SERPINI2 gene encodes a member of a family of proteins that acts as inhibitors of serine proteases. These proteins function in the regulation of a variety of physiological processes, including coagulation, fibrinolysis, development, malignancy, and inflammation. Expression of the encoded protein may be down-regulated during pancreatic carcinogenesis. Alternative splicing results in multiple transcript variants for this gene.

Full-length mature form of human SERPINI2 cDNA (19 - 405 aa, Isoform-II, derived from BC027859) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
