Delmar Division of Thomson Learning. 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 quanitation antibody.

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.

The antigen diffuses radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and immunodiffusjon antigen.

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

Radial immunodiffusion

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. 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. Retrieved from ” https: A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline.

The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increase with time. Antigen-antibody complexes are small and soluble when in antigen excess. 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.
