Immunochemical quantitation of antigens by single radial immunodiffusion. – Semantic Scholar

A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline. The molten medium is then poured onto a microscope slide or into an open container, such as a Petri dishand allowed to cool and form a gel. The antigen diffuses radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and the antigen.

The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increase with time. Delmar Division of Thomson Learning. American Society for Microbiology.

Radial immunodiffusion

Radial immunodiffusion RID or Mancini method, Mancini immunodiffusion or single radial immunodiffusion assay, is an immunodiffusion technique used in immunology to determine the quantity or concentration of an antigen in a sample. Immunoassays in Coagulation Testing. Immunoprecipitation Chromatin immunoprecipitation Immunodiffusion Ouchterlony double immunodiffusion Radial immunodiffusion Immunoelectrophoresis Counterimmunoelectrophoresis.

Therefore, precipitation near the center of the circle is usually less dense than it is near the circle’s outer edge, where antigen is less concentrated. Medical quwntitation used in immunology and for inflammation CPT — Antigen-antibody complexes are small and soluble when in antigen excess. Webarchive template wayback links CS1 maint: Measurements of large circles are more accurate than are those of small circles.
