The enzyme system of ELISA consists enzyme which is labeled to a specific antibody or antigen and a chromogenic substrate that is added after the antigen-antibody reaction. The substrate is hydrolyzed by the enzyme attached to antigen-antibody complexes.

This fully-resourced lesson describes how antibodies are used in the enzyme-linked immunosorbent assay (ELISA) test. The PowerPoint and accompanying resources are part of the last lesson in a series of 7 which have been designed to cover the details within point 2.4 of the AQA A-level specification. ELISA (Enzyme-Linked ImmunoSorbent Assay) is an immunologic technique used to detect the presence and concentration of an antigen or antibody in a sample. The power of an ELISA is based on the extreme specificity of the antigen-antibody interaction. ELISAs have wide-ranging applications, especially as medical diagnostic tools. Figure 1. ELISA .
The test requires: the antibodies fixed to a solid surface, such as the inner surface of a test tube; a preparation of the same antibodies coupled to an enzyme — one (e.g., β-galactosidase) that produces a colored product from a colorless substrate. Performing the Test The tubes are filled with the antigen solution (e.g., urine) to be assayed.
