Abstract
One of the major drawbacks of capillary electrophoresis (CE) and other microscale separation techniques, for the analysis of low abundant peptides and proteins in complex samples, are the poor concentration limits of detection. Several strategies have been developed to improve CE sensitivity. Here, we describe an on-line solid-phase extraction capillary electrophoresis mass spectrometry method with a commercial C18 sorbent for clean-up and preconcentration of neuropeptides from highly diluted biological samples.

Abstract
This study reported a pH-mediated stacking CE coupled with ESI MS/MS method to determine the phosphorylation sites of three synthetic phosphopeptides containing structural isomers. These phosphopeptides mimic the phosphopeptides (amino acid residues 12-25) derived from the trypsin-digested products of human lamin A/C protein. The LODs were determined to be 118, 132 and 1240 fmol for SGAQASS(19)TpPL(22)SPTR, SGAQASS(19)TPL(22)SpPTR, and SGAQASS(19)TpPL(22)SpPTR, respectively. The established method was employed to analyze the phosphorylation sites of the trypsin-digested products of glutathione S-transferase-lamin A/C (1-57) fusion protein that had been phosphorylated in vitro by cyclin-dependent kinase 1. The results indicated that this method is feasible to specifically determine the phosphorylation site from phosphopeptide isomers in the trypsin-digested products of a kinase-catalyzed phosphoprotein, which should benefit the investigation of protein kinase-mediated cellular signal transduction.

Abstract
The typical difficulties associated with the detection of acidic peptides (i.e., those with low isoelectric points (pI)) by matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS) represent a challenge in some proteomic analyses. Here, reverse micelle-forming amphiphilic homopolymers with positively charged interiors are synthesized and used to selectively enrich low pI peptides from complex mixtures for MALDI-MS detection. When using these polymers, acidic proteolytic peptides that are undetectable during normal MALDI-MS analysis are selectively detected. We show that enrichment of these low pI peptides allows acidic proteins to be selectively targeted for detection in multiprotein digests. In addition, the presence of the positively charged polymers during MALDI-MS analyses enhances peptide ion signals by almost an order of magnitude, thereby achieving reproducible ion signals for acidic peptides at concentrations as low as 100 fM. Concurrent detection of acidic and basic peptides was also facilitated by utilizing a sequential extraction process involving reverse micelle forming polymers with positively and negatively charged interiors.

Abstract
We have designed and fabricated a polydimethylsiloxane (PDMS) microfluidic device for coupling capillary electrophoresis (CE) and matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS). The coupling is advantageous in biological research because CE has the power of separating analytes in a sample based on mobility difference and MALDI-MS provides accurate and sensitive mass analysis of the analytes. The goal is realized by fractionating the separated analytes inside the microfluidic device and pushing the analyte fractions into open reservoirs. Each analyte fraction is then mixed with a matrix solution and deposited on a MALDI target for MALDI-MS. Therefore, a two-step analysis of analytes in the form of CE-MALDI-MS is achieved by using the microfluidic device.

Abstract
In the postgenomic era, proteomics has become a dominant field for identifying and quantifying the complex protein machinery of the cell. The expression levels, posttranslational modifications, and specific interactions of proteins control the biology of such processes as development, differentiation, and signal transduction. Studies of the proteins involved in these processes often lead to a better understanding of biology and of human disease. Powerful separation techniques and sensitive detection methods enable researchers to untangle these complicated networks of processes. CE coupled with either MS or LIF are two of the techniques that make this possible. This review will cover proven CE-based methods for proteomics on the cell and tissue level and their application in biological and clinical studies, relevant new developments in enabling technology such as microfluidic CE-MS demonstrated on model systems, and comment on the future of CE in proteomics.

Abstract
Metal affinity capture tandem mass spectrometry (MAC-MSMS) is evaluated in a comparative study of a lysine-derived nitrilotriacetic acid (N(alpha), N(alpha)-bis-(carboxymethyl)lysine, LysNTA) and an aspartic-acid-related iminodiacetic acid (N-(4-aminobutyl)aspartic acid, AspIDA) as selective phosphopeptide detection reagents. Both LysNTA and AspIDA spontaneously form ternary complexes with Ga(III) and phosphorylated amino acids and phosphopeptides upon mixing in solution. Collision-induced dissociation of positive complex ions produced by electrospray produces common fragments (LysNTA + H)(+) or (AspIDA + H)(+) at m/z 263 and 205, respectively. MSMS precursor scans using these fragments as reporter ions allow one to selectively detect multiple charge states of phosphopeptides in mixtures. It follows from this comparative study that LysNTA is superior to AspIDA in detecting phosphopeptides, possibly because of the higher coordination number and greater stability constant for Ga(III)-phosphopeptide complexation of the former reagent. In a continuing development of MAC-MSMS for proteomics applications, we demonstrate its utility in a post-column reaction format. Using a simple post-column-reaction 'T' and syringe pump to deliver our chelating reagents, alpha-casein tryptic phosphopeptides can be selectively analyzed from a solution containing a twofold molar excess of bovine serum albumin. The MAC-MSMS method is shown to be superior to the commonly used neutral loss scan for the common loss of phosphoric acid.
