counterimmunoelectrophoresis

[¦kau̇nt·ər¦im·yə·nō·i‚lek·trō·fə′r ē·səs]
(immunology)
Immunoelectrophoresis which uses two wells of application, one above the other, along the electrical axis—the anodal well filled with antibody and the cathodal with a negatively charge antigen; electrophoresis results in the antigen and antibody migrating cathodally and anodally, respectively, and a line of precipitation appears where the two meet.
