The present invention relates to an antibody conjugated peptide substituted with an amino acid having a photoreactive functional group, a physiologically active substance modified with the conjugated peptide, and an antibody-physiologically active substance conjugate in which an antibody is bound to the physiologically active substance. When the bioactive substance modified with the conjugated peptide is bound to the antibody, the binding efficiency between the antibody and the bioactive substance is significantly improved compared to the conventional one, so that the drug can be firmly bound without impairing the specificity of the antibody. It can accelerate the commercialization of bioactive substance conjugates. |
