<p>When an immunochemical assay of human chorionic gonadotropin (hCG) involving the use of an antibody supported on a carrier, an antigen and an antibody labeled with a labeling agent with the proviso that said supported antibody and the labeled antibody are dissimilar antibodies which are not overlapping with each other in antigen-determinant position, that the supported antibody is an antibody specifically reactive to hCG, said labeling agent is peroxidase, and that the peroxidase is coupled with the corresponding antibody with a compound of the formula: <CHEM> wherein n is an integer of 0 to 5 and R is a chemical bond or a divalent 6-membered cyclic hydrocarbon residue, a high reproducibility of measurement of hCG is obtained.</p> |
