Biological techniques and tools Immunologic tests. For most antigens, the area and the square of the immknodiffusion of the circle at the circle’s end point are directly proportional to the quantity of antigen and are inversely immunoeiffusion to the concentration of antibody.

Antigen-antibody complexes are small and soluble when in antigen excess. A solution containing antibody is added to a heated medium such as agar or agarose immmunochemical in buffered normal saline.
The antigen diffuses radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and the antigen. Ikmunochemical of Immunologic Techniques: American Association for Clinical Chemistry. 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.

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