| 摘要 |
The present invention provides a method for quantifying a monoclonal antibody, comprising the steps of: bringing a porous body in which the monoclonal antibody to be measured is immobilized onto pores thereof into contact with microparticles having a specific protease immobilized thereonto, thereby selectively digesting the monoclonal antibody with the protease; and detecting a peptide fragment resulting from the digestion, wherein the peptide fragment contains amino acid residues derived from a CDR2 domain in a heavy chain or a light chain of the monoclonal antibody. |
