reaction of identity

reaction of identity
a reaction pattern seen in double diffusion in two dimensions: the precipitin lines between the antigen wells and the antiserum well stop at their point of intersection, indicating that the antigen samples are identical. See also r. of nonidentity and r. of partial identity. See illustration.

Double diffusion used to indicate the relationship between antigens (blue, with numerals indicating epitopes present) and a particular test antibody (yellow). (Top), Reaction of identity; the antibody is precipitating identical epitopes in each preparation. (Middle), Reaction of nonidentity; the antibody preparation distinguishes the three different antigens, each of which forms an arc. (Bottom), Reaction of partial identity; the antibody preparation reacts with both epitopes, forming a line of identity (anti–epitope 1) with the addition of a spur of nonidentity (anti–epitope 2).
