蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The mature form of HGF is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. The protein has a calculated MW of 81.6 kDa (α chain 53.7 kDa and β chain 27.9 kDa). The protein migrates as 80-90 kDa (alpha & Beta chain), 58-63 kDa (alpha chain), 33 kDa (Beta chain) when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

背景（Background）
Hepatocyte growth factor (HGF) is a paracrine cellular growth, motility and morphogenic factor. Activating ligand for the receptor tyrosine kinase MET by binding to it and promoting its dimerization. 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. In addition, HGF has been implicated in a variety of cancers, including of the lungs, pancreas, thyroid, colon, and breast.
