Antibody-antigen interactions in gels

Immunoprecipitation can also be carried out in gds, resulting in the formation of precipitated bands which can be visualised dther directly, or by staining. These approaches have been largely superseded by techniques based on ELISA and Western analysis. 

In the Ouchterlony method, the double diffusion experiment is carried out with a central well containing the antibody or antibody mixture, surrounded by a circular 

Antigen solutions are loaded into wells in an pitin bands form in a rocket shape whose area is
