However, despite the availability of these tools, and the advantages of using targeted MS to validate promising biomarker candidates identified using MS based discovery experiments, a recent survey of the literature revealed that a large majority of discovery efforts lack validation, and those that are validated utilize immunoassays and not MS [Citation179]. For some analyses that are routinely performed there is still some guess work involved, or at least incorporation of algorithms that make assumptions about the data that is being used as a database or to interpret downstream analyses. One example of this is the recent exploration of dark matter material in our genome, or the genome/proteome of an individual that does not confer to the traditional paradigm of proteins being produced due to canonical translation events. Lomenick, B. et al. An alternative strategy is to analyze candidate transcript expression within databases specialized in normal tissue expression, such as the Genotype-Tissue Expression (GTEX) project. 11, 1124.e4 (2020).

Shao, W. et al. In addition, reduced sample complexity is often correlated with easier data analysis (no chemical tag modification to add to the search parameters, no deconvolution of data needed as is required with a multiplexing approach). Through successive rounds of single molecule fluorescence detection and Edman degradation, peptides are monitored to detect losses in fluorescence which indicate a labeled amino acid has been cleaved. 17, 659664 (2010). Technical issues such as analytical platform changes, e.g., shotgun proteomics to targeted MRM also contribute to lack of translation.

Recent advances in single-cell proteomics & single protein molecule sequencing have the potential to revolutionize biomedical research by enabling accurate characterization and quantitation of translational and post translational events on cellular samples from challenging sources, for example, from rarer cell types as well as from low quantity clinical materials. At present, proteomics is used pre-clinically for target identification and characterization, drug candidate selection and characterization, and clinically for biomarker discovery and development. In this review, we describe these areas of innovation, and discuss where the fields are headed in terms of fueling biotechnological and pharmacological research and discuss current gaps in the proteomic technology landscape. Recently, multiple IDA approaches have addressed this limitation by performing a real time database search (RTS) and only performing the slower, more accurate quantitative scans when a peptide is confidently identified [Citation28,Citation29].
