Recombinant Human AHSG Protein

Product Name: Recombinant Human AHSG Protein
Catalog #:  HRP-1505
Manufacture:  LD Biopharma, Inc.
Intruduction:

Alpha2-HS glycoprotein (AHSG), a glycoprotein present in the serum, is synthesized by hepatocytes. The AHSG molecule consists of two polypeptide chains, which are both cleaved from a proprotein encoded from a single mRNA. It is involved in several functions, such as endocytosis, brain development and the formation of bone tissue. The protein is commonly present in the cortical plate of the immature cerebral cortex and bone marrow hemopoietic matrix, and it has therefore been postulated that it participates in the development of the tissues. However, its exact significance is still obscure. Recent data indicated that GSN is auto-antigen, which its specific antibody could be detected in Rheumatoid Arthritis patient’s synovial fluid.

Full-length mature human AHSG (19-367 aa, derived from BC048198) gene was constructed with 29 aa N-terminal T7 / His / TEV cleavage site Tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
