[THE USE OF THE COMMERCIAL APPARATUS DUAL GEL MODULE FOR THE TWO-DIMENSIONAL POLYACRYLAMIDE GEL ELECTROPHORESIS]
Abstract:
Two-dimensional gel electrophoresis, continues to be one of the fundamental methods to study the biological protein diversity. This method described by O'Farrell in 1975 includes two following steps: isoelectric focusing in the first dimension and polyacrylamide gel electrophoretic fractionation of proteins according to their molecular weight in the second dimension. In this manuscript we described several technical parameters of the commercial apparatus Dual Gel Module for the gel electrophoresis by means of which it is possible to accomplish the electrophoretic protein fractionation in both dimensions. The distribution of the highly purified commercial proteins used as molecular standards in the detection system of the apparatus Dual Gel Module was identical to the commercial strips of the device GE Healthcare, USA.

Two-dimensional Gel Electrophoresis
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact...
