Abstract:

Single-cell proteomics allows revealing precisely the differences of proteins between individual cells, which has become a research hotspot showing indispensable application value in many important fields. Its difficulties lie in the fact that the proteins in a single cell are of extremely low abundance, which calls for ingenious solutions to the problems of sample loss during preparation, low sensitivity of chromatography-mass spectrometry detection, and insufficient analysis of spectral data with low signal intensities. This review summarizes the current research progress of mass spectrometry-based single-cell proteomic analysis, including single-cell sorting, sample preparation, chromatography-mass spectrometry acquisition, and data analysis, as well as its applications in biomedical fields. Its potential future development is also discussed.

Key words: Mass spectrometry, Proteomics, Single-cell, Microfluidics, Data-independent acquisition
