Precipitation ring test

PRECIPITATION RING TEST

  • The antigen is carefully layered over the antiserum, without mixing so that an interface is formed.
  • Diffusion of each reagent will then occur into each other. If the system is homologous, precipitation will occur at the point , where the proper ratio of antigen to antibody is reached.
