Description
Since the completion of the Human Genome Project, much has been made of the need to bridge the gap from genes and traits. As a key nexus for the many interacting ‘-omes’ (genome, transcriptome, proteome, metabolome, etc.), the proteome should offer a tight link between genotype and phenotype. Proteoforms, or all of the precise molecular forms of a protein, capture all sources of variability in protein composition (i.e., SNPs, isoforms, post-translational modifications), and thus provide crucial insights into regulation and function. Now, “single ion” mass spectrometry is poised to convert genes to proteoform signatures at a far faster rate. Recently we developed proteoform imaging mass spectrometry (PiMS), with individual ion mass spectrometry. This platform has been extended now to single-cell Proteoform imaging Mass Spectrometry (scPiMS), boosting cell processing rates by >20-fold in the field while detecting proteoforms from single cells.
