Gel Electrophoresis
Electrophoresis is the migration of charged particles or molecules in an electric field. This occurs when the substances are in aqueous solution. The speed of migration is dependent on the applied electric field strength and the charges of the molecules. Thus, differently charged molecules will form individual zones while they migrate. In order to keep diffusion of the zones to a minimum, elect...
متن کاملGel Electrophoresis
Electrophoresis is the main metod for separating large polyelectrolyte molecules, primarily used on DNA, in biochemistry and medicine research. An overwiev of the models of physical mechanisms that are behind this phenomena will be presented. The prominent role is taken by reptation mechanisms, by which large exible polyelectrolytes thread their way through the pores of the gel matrix. There a...
متن کاملGel Electrophoresis
The separation of polypeptides by electrophoresis allowed Arne Tiselius to describe protein fractions corresponding to albumin, -, -, and -globulins in serum with the Rrst published diagram of human serum protein electrophoresis in 1939. The number of fractions slowly expanded into electrophoretic subfractions identiRed as 1, 2, 1, 2, 1 and 2. The mobility characteristics of these fractions are...
متن کاملGel Electrophoresis in Capillary Electrophoresis
The discovery that antigen}antibody interaction could be produced not only in liquids, but also on gel media, such as agar or agarose gels, with the formation of insoluble immunoprecipitates, opened the door to the development of the gel diffusion techniques for immunoprecipitation analysis. The Rrst of these techniques, known as double diffusion, was introduced by Ouchterlony in 1948. In this ...
متن کاملDiscontinuous electrophoresis on polyacrylamide gel slab.
D ISCOT1XUOUS ELECT1IO1’HORESIS in polyacrylamide rods has been used for separation of serum proteins (1). In spite of satisfactory resolution in tile rod, the technic renhains cumbersome, and comparison of the closely migrating cOnlpoflents inaccurate. Akroyd (2) reported discontinuous electrophoresis On polyacrylamide gel slab, which alleviates many of the difficulties of the rod. We llave co...
