title: The role of liquid chromatography in proteomics.
abstract: Proteomics represents a significant challenge to separation scientists because of the diversity and complexity of proteins and peptides present in biological systems. Mass spectrometry as the central enabling technology in proteomics allows detection and identification of thousands of proteins and peptides in a single experiment. Liquid chromatography is recognized as an indispensable tool in proteomics research since it provides high-speed, high-resolution and high-sensitivity separation of macromolecules. In addition, the unique features of chromatography enable the detection of low-abundance species such as post-translationally modified proteins. Components such as phosphorylated proteins are often present in complex mixtures at vanishingly small concentrations. New chromatographic methods are needed to solve these analytical challenges, which are clearly formidable, but not insurmountable. This review covers recent advances in liquid chromatography, as it has impacted the area of proteomics. The future prospects for emerging chromatographic technologies such as monolithic capillary columns, high temperature chromatography and capillary electrochromatography are discussed.
