ABSTRACT:
The present invention provides a branched polyalkylene glycol wherein three or more single-chain polyalkylene glycols and a group having reactivity with an amino acid side chain, the N-terminal amino group or the C-terminal carboxyl group in a polypeptide or a group convertible into the group having reactivity are bound; and a physiologically active polypeptide modified with the branched polyalkylene glycol.
