immuno-electrophoresis A technique for the differentiation of proteins in solution, based on both their electrophoretic and immunological properties. Initially the proteins are separated by gel electrophoresis: they are then reacted with specific antibodies by double diffusion through the gel. The pattern of precipitating arcs thus formed can be used to identify the proteins.
