title: Combination of three techniques for the study of complex enzyme mixtures: polyacrylamide gel electrophoresis, immunodiffusion and detection of enzymatic activity.
abstract: A technique is presented in which two different separation methods are combined. The first separation is carried out in polyacrylamide gel electrophoresis, which is then followed by immunodiffusion in agarose against appropriate antisera. Soluble and insoluble macromolecular carbohydrates were used as substrates in the detection of the various enzymatic activities. These three methods in combination can provide new information on enzymatically active proteins in mixtures, such as isoenzymes, and multiple forms varying in molecular size.
