Abstract
Mixtures of monoclonal antibodies which contain effective assaying amounts of each of at least two monoclonal antibodies that bind to different antigenic sites on the antigen and are capable under appropriate conditions of binding simultaneously to an antigen are useful in enhanced sensitivity assays for the antigen. By utilizing such mixtures in diagnostic assays for important antigens such as the polypeptide human chorionic gonadotropin enhanced sensitivity can be achieved as compared with assays employing individual monoclonal antibodies.
