This chapter has presented several comprehensive 2DLC approaches combining a first-dimension IEX separation and a second-dimension RP separation for the analysis of complex protein mixtures typical in proteomics studies. Online ESI-TOF/MS detection provided sensitive detection and valuable qualitative information (MW) for proteins eluting from the MDLC system. Coordinated fraction collection and subsequent MS analysis of peptides produced by proteolysis of the fractions provided in-depth information on protein identification and a mechanism... 

When fresh or frozen tissue is used for proteomic analyses, the results cannot be related directly to the clinical course of diseases in a timely manner. Instead, researchers frequently reduce the number of interesting proteins to a manageable number and then attempt to use immunohistochemistry to understand the implications of proteomic changes in archival formalin-fixed, paraffin-embedded (FFPE) tissue for which the clinical course has been established.3 Unfortunately, immunohistochemistry is a semiquantitative pro-teomic method, and the choice of interesting proteins must occur without advance knowledge of the clinical course of the disease or the response to therapy. If routinely fixed and embedded archival tissues could be used for standard proteomic methods such as 2-D gel electrophoresis and mass spectrometry (MS), these powerful techniques could be used to both qualitatively and quantitatively analyze large numbers of tissues for which the clinical course has been established. However, analysis of archival FFPE tissues by...

The main goal of the proteomic research is to find the distinction between quantitative regulation and structural proteomics. Today, the core technology of proteomics is 2DE (two-dimensional electrophoresis) coupled with MS (mass spectrometry). It offers the most widely accepted way of gathering qualitative and quantitative protein behavioral data in cells, tissues, and fluids to form proteomic databases. 

Mass spectrometry (MS) is playing an increasingly visible role in the molecular characterization of combinatorial libraries, natural products, drug metabolism and pharmacokinetics, toxicology and forensic investigations, and proteomics. Toward this end, electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo-ionization (APPI) have proven valuable for both qualitative and quantitative screening of small molecules (e.g., pharmaceutical products) [9-14]. 

Proteomics The study of the proteome not technology limited the qualitative and quantitative study of the proteome under various conditions including protein expression, modification, localization, function, and protein-protein interactions, as a means of understanding biological processes.
