Gel Electrophoresis

چکیده
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, electrophoresis is carried out in an anticonvective medium such as a viscous fluid or a gel matrix. Therefore, the speed of migration is also dependent on the size of the molecules. In this way fractionation of a mixture of substances is achieved with high resolution.

A Simpler and Faster Version of Two-Dimensional Gel Electrophoresis Using Vertical, Mini SDS-PAGE Apparatus
We have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-DE). This modified version of 2-DE is not only simpler and easier but also faster than all the currently available methods. In this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrop...

Using a Temperature Gradient against the Time in Polyacrylamide Gel Electrophoresis May Eliminate the Need for Stacking Gels
Background and Objectives: Making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. Considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity. Ultimately, a downward tempera...
