Abstract: In-gel digestion is the important step that connects electrophoresis separation and mass spectrometry identification in proteome research, and can significantlyaffect the results of qualitative and quantitative analysis of proteins. The technology was firstly proposed in 1992, and from then on, many progresses have been made and various improvement plans have been developed. In order to more effectively use the technology of in-gel digestion, the progress on the aspects of gel decoloration, impurity removal, protein digestion and peptides extraction were reviewed from the literature.

Key words: in-gel protein digestion, sample preparation, mass spectrometry, electrophoretic separation, technical progress
