  • Publication number: 20220118050
    Abstract: A polyethylene glycol-modified form of a hepatocyte growth factor or an active fragment thereof achieves both an in vivo half-life extending effect of polyethylene glycol modification and the retainment of bioactivity. The polyethylene glycol-modified form of a hepatocyte growth factor or an active fragment thereof has one molecule of forked-type polyethylene glycol covalently bound to two molecules of the hepatocyte growth factor or the active fragment thereof at each of their respective carboxyl-terminal regions to form a homodimer.
