HRP-1504 Recombinant Human Gelsolin Protein $300

Recombinant Human Gelsolin Protein

Product Name: Recombinant Human Gelsolin Protein
Catalog #:  HRP-1504
Manufacture:  LD Biopharma, Inc.

The protein encoded by human gelsolin (GSN) gene binds to the 'plus' ends of actin monomers and filaments to prevent monomer exchange. The encoded calcium-regulated protein functions in both assembly and disassembly of actin filaments. Defects in this gene are a cause of familial amyloidosis Finnish type (FAF). Multiple transcript variants encoding several different isoforms have been found for GSN gene. 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 GSN (730 aa, Isoform-b, derived from BC026033) 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.
