  • antibody
  • Radial immunodiffusion (RID) is a quantitative variation of the Ouchterlony technique (immunodiffusion) in which the agar gel contains evenly distributed antigen (or antibody) and its counterpart from the test sample diffuses into the gel from a single well resulting in a circular precipitin line around the sample well.

  • The diameter of the precipitin ring is proportional to the concentration of the antibody (or antigen) present in the test sample. (specialtylabs.com)
  • By comparing the diameter of the test specimen precipitin ring to known standards, a relatively insensitive estimation of the concentration of specific antibody or antigen can be achieved. (specialtylabs.com)
