The coming years will define how applicable this approach is within a drug development or clinical setting, but the studies such as the one described here are an example of how this approach could relate to important disease models. From the BEST document, validation, for biomarkers and clinical outcome assessments, is a process to establish that the performance of a test, tool, or instrument is acceptable for its intended purpose. It is important to demonstrate that the test measures what it was intended to measure (analytical validation) and that the biomarker (through its test) has the ability to predict or measure the relevant clinical concept. Eberl, H. C. et al. This Review provides an excellent analysis of discovery strategies and molecular mode of action of approved drugs. However, due to each candidate peptide being analyzed twice, this approach decreases instrument duty cycle and ultimately proteomic depth.

Proteomics-Driven Drug Discovery Effective Use of Chemoproteomics, Chemical Biology, and Phenotypic Screening September 26-27, 2023 While finding novel druggable targets and drug modalities for therapeutic intervention remains a top priority for the pharma/biotech industry, identifying and validating "good" targets and leads remains challenging. J. Choobdar, S. et al. Fluorescent labels are added to specific amino acid side chains (e.g., lysine or cysteine) before peptides are affixed to a microscope slide. Taken together, since translational and post-translational events are primary readouts for the cells biological functionality, we expect that proteomics will remain a key technology in the pharmaceutical and biotechnological arena in the coming decade. Such a "random" approach entails testing numerous compounds and developing countless highthroughput screening assays. Noncoding regions are the main source of targetable tumor-specific antigens.

For a detector such as the Orbitrap, the typical dynamic range is about 56 orders of magnitude, whereas peptide and protein concentrations can span > 10 orders of magnitude in a given biological matrix, for example a tumor sample, cell line or biological fluid such as plasma. However, this does mean that it is standard to only identify less than half of the spectra in a typical bottom up workflow. The dynamics of protein complexes also remains a technologically challenging arena. The next generation sequencing (NGS) field has recently bloomed, encompassing a variety of tools to decipher the content of the mRNA, nucleic DNA and epigenetic events associated with single cells and is now considered an essential technology for unraveling biological mechanisms [Citation24]. 9, 11811190 (2017).
