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. Webarchive template wayback links CS1 maint: American Society for Antigns.

The antigen immunocbemical radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and the antigen. Laboratory Techniques; Chapter For most antigens, the area and the square of the diameter of the circle at the circle’s end point are directly proportional to the quantity of antigen and are inversely proportional to the concentration of antibody.

Retrieved from ” https: 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. Measurements of large circles are more accurate than are those of small circles.

Rose, Noel; Friedman, Herman, eds. While circles are still expanding, a graph that compares the quantities or concentrations of the antigen on a logarithmic scale with the diameters or areas of the circles on a linear scale may be a straight line kinetic method.

Expansion of the circle reaches an end point and stops when free antigen is depleted and when antigen and antibody reach equivalence.

Proceedings of the 11th Colloquium. A solution containing antibody is added to a heated medium such quanttation agar or agarose dissolved in buffered normal saline.

Retrieved — via Google Books. 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. Protides of the Biological Fluids: The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increase with time.

Circles that small quantities of antigen create reach their end points before circles that large quantities create.
