In the last decade, single cell RNA sequencing has advanced our understanding of transcript heterogeneity. Currently, there are strong efforts to enable single cell proteomic analysis using mass spectrometry (MS)-based workflows. While the analysis of single-cell-sized aliquots from bulk-prepared tryptic digests has been demonstrated, only recently have label-free strategies been reported for profiling hundreds of proteins from single mammalian cells. Further development in sample processing, separations, MS and data analysis are necessary to realize single cell proteomics with greater depth of coverage and quantitative accuracy. Here we introduce an improved LC separation coupled to the new Thermo Scientific™ Orbitrap Eclipse™ Tribrid™ mass spectrometers with a Thermo Scientific™ FAIMS Pro™ interface to increase proteome coverage for single mammalian cells.
