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

Expansion of the circle reaches an end point and stops when free antigen is depleted and when antigen and antibody reach equivalence. Manual of Clinical Immunology 2nd ed.

Webarchive template wayback links CS1 immunodiffusuon 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 immunodiffksion antigen and can thereby be used to quantitate the amount of antigen.


Archived at the Wayback Machine. The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increase with time. 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.

Laboratory Techniques; Chapter Circles that small quantities of antigen create reach their end points before circles that large quantities create.

Rose, Noel; Friedman, Herman, eds. A solution containing antibody is added to a immunodiffusiin medium such as agar or agarose dissolved in buffered normal saline. From Wikipedia, the free encyclopedia. Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes.

Retrieved — via Google Books. 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.

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. Antigen-antibody complexes are small and soluble when in antigen excess. Access a collection immunodlffusion Canadian resources on immunodiffusiom aspects of English and French, including quizzes.
