Single Cell Proteoform Analysis Using scPiMS

ABSTRACT: We introduce single-cell Proteoform imaging Mass Spectrometry (scPiMS), which realizes the benefit of direct solvent extraction and MS detection of intact proteins from single cells drop casted onto glass slides. Sampling and detection of whole proteoforms by individual ion mass spectrometry enables a scalable approach to single-cell proteomics. This new scPiMS platform addresses the throughput bottleneck in single cell proteomics and boosts cell processing rate by several fold while accessing protein composition with higher coverage.
