Nano-LC/MS/MS-based analytical system for single-cell analysis
Analytical methods to accurately identify and quantify comprehensive metabolites or proteins from single mammalian cells are still in development. The aim of this study was to develop a single-cell metabolomic and proteomic analytical system based on highly sensitive nano-liquid chromatography tandem mass spectrometry (nano-LC/MS/MS). We firstly developed a method called in-line sample preparation for efficient cellular metabolomics or proteomics (ISPEC). By combining live single-cell sampling, ISPEC, and nano-LC/MS/MS, we successfully detected approximately 50 metabolites or 300 proteins from single cells. Our single-cell proteomic and metabolomic analytical system represents a potentially useful tool for in-depth studies focused on cell metabolism and heterogeneity.
