Recombinant Human IGFBP6 Protein

Product Name: Recombinant Human IGFBP6 Protein
Catalog #:  HRP-0823
Manufacture:  LD Biopharma, Inc.

Insulin-like growth factor binding proteins (IGFBP) 1–6 bind IGFs with high affinity in extracellular fluids and regulate IGF actions at target tissues. Some IGFBPs also possess distinct biological actions that are independent of IGFs. IGFBP6 is unique among the six IGFBPs because of its 50-fold greater affinity for IGF-II, making it a relatively specific inhibitor of IGF-II actions. Recent studies suggest that IGFBP-6 is a tumor suppressor that inhibits the growth of a number of IGF-II-dependent tumors. In addition to its ability to bind and sequester IGF-II, recent in vitro studies suggest that IGFBP-6 also has IGF-independent actions such as responding to hypoxia induction for inhibiting vascular endothelial cells angiogenesis in vitro.

Full-length human IGFBP6 (28-340 aa) gene was constructed with 15 aa N-terminal T7 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.
