Laboratory Techniques; Chapter In which subject field? 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.

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. Diagnostic immunology Nephelometry Complement fixation test Immunocytochemistry Immunohistochemistry Direct fluorescent antibody Epitope mapping Skin allergy test Patch test.

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.

A solution containing antibody is added to a heated medium such as agar or agarose dissolved in buffered normal saline. Biological techniques and tools Immunologic tests. 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.

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

AmsterdamThe Netherlands: 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.
