electroimmunodiffusion

electroimmunodiffusion
An immunochemical method that combines electrophoretic separation with immunodiffusion by incorporating antibody into the support medium.

elec·tro·im·mu·no·dif·fu·sion (e-lek″tro-im″u-no-dĭ-fuґzhən) the combination of immunodiffusion with electrophoresis, using an applied electric field to speed up the migration of antigen and antibody. Two such techniques have achieved widespread use: counterimmunoelectrophoresis (one-dimensional double electroimmunodiffusion) and Laurell rocket immunoelectrophoresis (one-dimensional single electroimmunodiffusion).
