Here, they employed the use of an Evotip for sample clean up and eluted peptides directly for separation and mass spectrometric analysis in one integrated procedure. Mass spectrometry-based proteomics in preclinical drug discovery. Novel biochemical approaches, in combination with recent developments in mass spectrometry-based proteomics instrumentation and data analysis pipelines, have now enabled the dissection of disease phenotypes and their modulation by bioactive molecules at unprecedented resolution and dimensionality. The phenotypic approach to drug discovery falls within the realm of target deconvolution, and involves exposing cells, isolated tissues, or animal models, to small molecules to determine whether a specific candidate molecule exerts the desired effect - which is observed by a change in phenotype.

Gupta, G. D. et al. In addition, for any given approach run in an unbiased fashion for de-novo target deconvolution, success is to some extent target-dependent, i.e., not every binding event leads to detectable thermal stabilization or conformational change under the selected set of experimental conditions.

Approaches to multiplex past 30-plex samples in parallel have been proposed [Citation183], but at this time have yet to become commercially available. The observation that the number of biomarker candidates identified in the literature is perhaps a quarter of human proteins, suggests that the candidate discovery process is often not rigorous enough [Citation133]. In many cases, prior knowledge can inform this decision, pointing toward high sensitivity methods for example if chemokines and cytokines are likely potential biomarkers. While the technologies underlying these platforms have yet to be revealed, it is clear that the coming years will unveil the possibilities of non-mass spectrometry based unbiased and untargeted single molecule sequencing proteomics approaches.
