Summary. Two-dimensional gel electrophoresis (2DGE) is a technique that can resolve thousands of biomolecules from a mixture. This technique involves two distinct separation methods that have been coupled together: isoelectric focusing (IEF) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).

Process of Gel electrophoresis:-The process of gel electrophoresis for the separation of DNA molecules takes place in the following manner:- 1) Using the restriction enzymes, DNA molecule is cut into small pieces or fragments. 2) The cut DNA fragments are moved to the wells or pots where agarose gel is already present. Polyacrylamide Gel Electrophoresis (PAGE) When electrophoresis is performed in acrylamide or agarose gels, the gel serves as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the gel’s pore structure allows smaller proteins to travel more rapidly than larger proteins (Figure 2.1).

The electric charge driving the electrophoresis is governed by the intrinsic charge on the protein at the pH of the running buffer. This charge will, of course, depend on the amino acid composition of the protein as well as post-translational modifications such as addition of sialic acids.
