immunodiffusion

 [im″u-no-dĭ-fu´zhun]
the diffusion of antigen and antibody from separate reservoirs to form decreasing concentration gradients in hydrophilic gels.

im·mu·no·dif·fu·sion

(im'yū-nō-di-fyū'zhŭn, im-ū'nō-),
A technique to study antigen-antibody reactions by observing precipitates formed by antigen-antibody complexes, which are combinations of specific antigen and antibodies separately placed in a gel and diffused.

(im'yū-nō-di-fyū'zhŭn)
A technique of studying antigen-antibody reactions by observing precipitates formed by combination of specific antigen and antibodies that have diffused in a gel in which they have been separately placed.
