A progression in technology development for proteomics research is occurring at an ever-increasing rate (1). The monitoring of the physiological changes of healthy and diseased tissues with linkage to the expression of the proteome is fast becoming a method to identify molecular disease targets for creating novel drugs, as well as providing data for basic research. Improvements in the preparation of protein samples and mass spectrometry (MS) equipment are leading to better identification and characterization of proteins (2,3). Advances in protocols for protein sample prefractionation, solubilization strategies, and two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) are oriented with the development of automated high-throughput proteomic analysis platforms (4, 5, 6).
