Question

Quizplus · Accepted Answer

Immunodiffusion is a diagnostic procedure that relies on the precipitation of antigen-antibody complexes. This technique is used to identify the presence of specific antigens or antibodies in a sample. It involves placing a sample containing the antigen and a corresponding antibody in a gel medium, and allowing the antigen-antibody complexes to precipitate out of solution. This results in the formation of visible bands or lines, which can be used to identify the presence and concentration of the antigen or antibody in the sample.
