High-resolution two-dimensional gel electrophoresis and protein identification using western blotting and ECL
Abstract:
Two-dimensional gel electrophoresis has been the technique of choice for analyzing the protein composition of cell types, tissues and fluids and is a key technology in modern proteomics projects. Here we describe reproducible procedures for running isoelectric focusing and nonequilibrium pH gradient electrophoresis gels that are based on the carrier ampholyte technology originally described by O'Farrell. Moreover, we present a sensitive immunoblotting procedure that has been used routinely in our laboratory to determine the identity of hundreds of human proteins.

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.

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
SDS-PAGE
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 proteins...

Capillary Electrophoresis: Applications
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...
Southern Blot
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
