Analysis of proteins in complex mixtures such as cell lysates is presently performed by two‐dimensional polyacrylamide gel electrophoresis under denaturing conditions (denaturing 2‐D PAGE) followed by extraction of proteins from gel pieces and structural analysis of the proteins. This type of protein analysis is contributing to the correlation of information stored in DNA sequences with the structure of the product polypeptides. However, denaturing 2‐D PAGE has its own limitations and it is necessary to develop various methods of protein analysis to reconstruct the total structure and function of proteins in complex systems. This review article summarizes the work in our laboratory to explore proteins in human plasma combining various electrophoretic techniques: nondenaturing and denaturing 2‐D PAGE, capillary electrophoresis, and agarose gel isoelectric focusing.
