Protein-protein interactions (PPIs) play critical functional and regulatory roles in cellular processes. They are essential for macromolecular complex formation, which in turn constitutes the basis for protein interaction networks that determine the functional state of a cell. We and...

Application of Nontarget High Resolution Mass Spectrometry Data to Quantitative Source Apportionment.

Environmental science & technology

Peter KT, Wu C, Tian Z, Kolodziej EP.
PMID: 31603663
Environ Sci Technol. 2019 Nov 05;53(21):12257-12268. doi: 10.1021/acs.est.9b04481. Epub 2019 Oct 25.

High resolution mass spectrometry (HRMS) analyses provide expansive chemical characterizations of environmental samples. To date, most research efforts have developed tools to expedite labor- and time-intensive contaminant identification efforts. However, even without chemical identity, the richness of nontarget HRMS...

Candidate Gene Testing in Clinical Cohort Studies with Multiplexed Genotyping and Mass Spectrometry.
