Proteomics ultimately hinges upon protein identification to reveal the meaning behind the masses, spots, or peaks detected by other means. Because fraction collection is a natural component of HPLC separations, intact proteins can be readily collected either for direct analysis or for proteolytic digestion and identification using peptide mass fingerprinting (PMF) in conjunction with matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). [Pg.229]

The ability to resolve and characterize complicated protein mixtures by the combination of 2DLC and online mass spectrometry permits the combination of sample fractionation/simplification, top-down protein mass information, and bottom-up peptide level studies. In our lab, the simplified fractions generated by 2D(IEX-RP)LC are digested and analyzed using common peptide-level analysis approaches, including peptide mass fingerprinting (Henzel et al., 1993 Mann et al., 1993), matrix-assisted laser desorption/ionization (MALDI) QTOF MS/MS (Millea et al., 2006), and various capillary LC/MS/MS methodologies (e.g., Ducret et al., 1998). [Pg.308]

Two-dimensional electrophoresis [86] is a well established technique for the separation of intact proteins. In the first dimension the proteins are separated based on their isolectric point while the second dimension separates them based on their size. The presence on the gel of the proteins is revealed by Coomassie blue or silver staining. Under favorable conditions several thousand spots can be differentiated. The gel is digitized and computer-assisted analysis of the protein spot is performed. The spots of interest are excised either manually or automatically and then digested with trypsin. Trypsin cleaves proteins at the C-terminal side of lysine and arginine. In general one spot represents one protein and the peptides are analyzed by MALDI-TOF to obtain a peptide mass fingerprint. A peptide mass fingerprint involves the determination of the masses of all pep-... [Pg.50]
