  • Publication number: 20240191272
    Abstract: A simpler ADC production method is provided. A method for producing an antibody-drug conjugate including the following step: the step of conjugating a glycan-homogenized antibody and a glycosylated drug. The glycosylated drug consists of a drug bound to a glycan having an oxazolinated reducing end via a linker. The glycan-homogenized antibody and the glycosylated drug can be conjugated with an endo-P-N-acetylglucosaminidase mutant enzyme.

  • 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.
