two-dimensional immunoelectrophoresis

two-·di·men·sion·al im·mu·no·e·lec·tro·pho·re·sis

a combination of conventional electrophoretic separation and electroimmunodiffusion; electrophoresis is first carried out, then the electrophoretic strip is placed on a second slide and an antibody-containing agarose solution is allowed to solidify adjacent to it; electrophoresis is then performed at right angles to the original separation.
