Abstract: A process for production of antibody conjugates which comprises modification of a part of the amino groups in an antibody or its fragment whose antigen-binding activity is lowered by the modification of its amino groups, with a reversible modifier for protein amino groups, reaction of the antibody or its fragment with a substance bearing a group reactive with the amino group and removal of the residues of the reversible modifier from the amino groups and, when necessary, the residues of the substance bearing a group reactive with the amino group in case they are introduced onto groups other than amino groups. The process according to the present invention gives antibody conjugates with retention of antigen-binding activity and these conjugates have a possibility of being used in affinity chromatography or as a diagnostic agent or a drug for cancer therapy.
