Abstract:

As a branch of proteomics, peptidome has been extensively applied in biomarker discovery, early diagnosis and pharmacy. In the research of peptidome, sample pretreatment plays a vital role. Here, we review the pretreatment approaches and techniques of peptidome, mainly including ultrafiltration, organic solvent precipitation, solid phase extraction and so on. The biggest challenge of the development of peptidome is the large number of high-abundance proteins in the sample. Therefore, there is an urgent need to develop the fast, efficient, high-throughput and automated sample preparation methods and techniques.

Key words: low-molecular weight proteins, peptides, peptidome, sample pretreatment
