Advances in hyphenated analytical techniques for shotgun proteome and peptidome analysis—A review Review Article

Proteomics is defined as the analysis of part or all of the protein components of a complex biological system (a cell, organ or tissue) at a given moment. Due to the huge number of proteins encoded by the genome, novel analytical techniques must be developed to meet the need of large scale analysis. This has led to the hyphenation of multiple techniques to achieve this object. Here current status of the hyphenated analytical techniques of one-dimensional and multidimensional liquid chromatography–mass spectrometry for shotgun proteomic analysis is reviewed, and on-line techniques for automated sample preparation and injection are also covered. In addition, the hyphenated techniques for peptidome analysis are also covered.
