Abstract
Disclosed is an improvement to a sandwich type immunoassay in which there is immobilized to a solid support an antibody which is specific to an epitope of the analyte whose presence or concentration is being sought and a first labeled antibody which is specific to another epitope of the analyte. The improvement involves providing a second labeled antibody which is specific to the first labeled antibody to thereby form a chain of two or more labeled antibodies which results in amplification of the signal generated upon formation of the sandwich.
