Identification of a primary target of thalidomide teratogenicity. In the proteomics community, we have traditionally navigated our bioanalytical analyses on the assumption that we understand the composition of the proteome. This begins with how a sample is collected in the laboratory or the clinic, how it is then prepared, derivatized and separated, to how it is analyzed both biophysically as well as via data analytics. & Whitty, A.

In addition to being a powerful tool for biomarker discovery, clinical proteomics can add significant value to drug discovery and development in many other ways independent of biomarkers. Various studies have been performed to probe the complex architecture that is the cell, including single-cell variations, dynamic protein translocations, changing interaction networks and proteins that can localize to various sub-cellular compartments, allowing researchers to further unravel human disease biology [Citation195,Citation196].

Biol. Boike, L. et al. Nat. Here, spectral libraries are created in silico and used to identify and quantify peptides from DIA spectra that may contain fragments from many peptides. Compound treatment of intact cells as reported so far for TPP is preferable since it reflects the pharmacologically relevant environment, exemplified by the fact that a study of the targets of ciprofloxacin in E. coli identified the known target DNA gyrase only in live cell experiments where intact DNA is present which is required for compound binding [Citation116].
