Homogeneous Immunoassay process using covalent conjugate of enzyme and plural monoclonal antibodies for different epitopes on analyte |
摘要 |
An enzyme-labelled antibody adapted for use in a homogeneous immunoassay is provided. The enzyme-labelled antibody is a conjugate of an enzyme with two or more different monoclonal antibodies, each of the monoclonal antibodies being capable of specifically recognizing and binding to a different epitope of the same antigen. By using the enzyme-labelled antibody in the homogeneous enzyme immunoassay process, an analyte can be quantitatively analyzed at a higher sensitivity through a simple operation. Also provided is a dry immunoassay element comprising an immunological reaction layer containing the enzyme-labelled antibody. By the provision of such an immunoassay element, a further simplified quick analysis of an analyte is realized to give an accurate result.
