Louisiana State University School of Medicine. Immunoassays in Coagulation Testing. American Society for Microbiology. Review of Immunologic Techniques: The antigen diffuses radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and the antigen.
AmsterdamThe Netherlands: Views Read Edit View history. Archived at the Wayback Machine. Retrieved from ” https: A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline. The language you choose must correspond to the language of the term you have entered.
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 immunodiffuusion antibody reach equivalence.
The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increase with time. Medical tests used in immunology and for inflammation Immunodiffusuon — Rose, Noel; Friedman, Herman, eds.
Antigen diffuses into the agar which contains specific antibody and a ring of precipitate is formed, the diameter of which is directly proportional to the concentration of the antigen and can thereby be used to quantitate the amount of antigen.

Measurements of large circles are more accurate than are those of small circles.

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.
