| abstract |
The present invention provides a block copolymer which can act as a carrier that can achieve both the stability of a biotechnology based drug in blood and the release of the biotechnology based drug at an affected area. The block copolymer according to the present invention comprises a polyamino acid chain segment and a hydrophilic polymer chain segment wherein the polyamino acid chain segment contains an amino acid residue having a cationic group in a side chain thereof and an amino acid residue having a phenylboronic acid group in a side chain thereof wherein at least one hydrogen atom in a phenyl ring in the phenylboronic acid group is substituted so that the resultant block copolymer can have a pKa value close to the physiological pH value. |
