HRP-1278 Recombinant Human Fibronectin FN3 Domain-8 Protein $200

Recombinant Human Fibronectin FN3 Domain-8 Protein

Product Name: Recombinant Human Fibronectin FN3 Domain-8 Protein
Catalog #:  HRP-1278
Manufacture:  LD Biopharma, Inc.

Extracellular matrix protein fibronectin (FN) plays an important role in cell adhesion. FN contains FN type I, II and III domains. The FN III repeat is generally about 90 amino acid long and is composed of seven b-strands, forming two antiparallel b-sheets. In the C-terminal of human fibronectin region, there are 16 FN-III repeat domains. FN III domain derived proteins have been demonstrated to bind various proteins with high affinity. To decode the biological function of each FN-III domain, all 16 FN-III domains were separately cloned and expressed in E.coli as soluble functional proteins. So coating them as matrix proteins in culture dish may provide a unique functional assay for regulating human ES cell lineage specific differentiation.

Full-length third FN-III domain of Human fibronectin cDNA was constructed by fully synthetic gene synthesis with codon optimization and expressed with N-terminal 206 aa of human Alpha fetal protein (AFP) fusion protein. This protein was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
