Miniaturized proteomics and peptidomics using capillary liquid separation and high resolution mass spectrometry Ramstrom M; Bergquist JFEBS Lett 2004[Jun]; 567 (1): 92-5Knowledge of the protein and peptide content in a tissue or a body fluid is vital in many areas of medical and biomedical sciences. Information from proteomic and peptidomic studies may reveal alterations in expression due to, e.g., a disease and facilitate the understanding of the pathophysiology and the identification of biological markers. In this minireview, we discuss miniaturized proteomic and peptidomic approaches that have been applied in our laboratory in order to investigate the protein and peptide contents of body fluids (such as plasma, cerebrospinal and amniotic fluid), as well as extracted tissues. The methods involve miniaturized liquid separation, i.e., capillary liquid chromatography and capillary electrophoresis, combined with high resolution mass spectrometry (MS), i.e., Fourier transform ion cyclotron resonance MS. These approaches provide the opportunity to analyze samples of small volumes with high throughput, high sensitivity, good dynamic range and minimal sample handling. Also, the experiments are relatively easy to automate.|*Proteome[MESH]|Animals[MESH]|Chromatography, Liquid/*methods[MESH]|Electrophoresis, Capillary/*methods[MESH]|Humans[MESH]|Mass Spectrometry/*methods[MESH]|Peptides/*chemistry[MESH]|Proteomics/*methods[MESH] |
