Human HGFAC Recombinant Protein (N-His) is a recombinant protein expressed in E. coli, spanning Glu103-Ser655, with an N-terminal His tag. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. Hepatocyte growth factor activator serine protease is a ~70 kDa protein. Serine protease that hydrolyzes the inactive zymogen hepatocyte growth factor (HGFsc) to an activated disulfide-linked heterodimer, then initiating hepatocyte growth factor receptor signaling pathway.
