Technical Data
Hepatocyte Growth Factor alpha Chain, Recombinant, Human (Hepatocyte Growth Factor, Hepatopoeitin-A, Scatter Factor, SF, HGF, HPTA)
Growth Factors, Cytokines Storage: -20CShipping: Blue Ice
Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase-signalling cascade. Hepatocyte growth factor is secreted by mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial origin. Its ability to stimulate mitogenesis, cell motility, and matrix invasion gives it a central role in angiogenesis, tumorogenesis, and tissue regeneration. It is secreted as a single inactive polypeptide and is cleaved by serine proteases into a 69kD alpha-chain and 34kD beta-chain. A disulfide bond between the alpha and beta chains produces the active, heterodimeric molecule.

Recombinant corresponding to aa32-494 from mature human HGF-A, fused to 6x His-tag at N-terminal, expressed in E. coli.
