Chemical cross-linking of proteins coupled with mass spectrometry analysis (CXMS) is widely used to study protein-protein interactions (PPI), protein structures, and even protein dynamics. However, structural information provided by CXMS is still limited, partly because most CXMS experiments use lysine...

Ion mobility (IM) mass spectrometry provides structural information about protein shape and size in the form of an orientationally-averaged collision cross-section (CCSIM). While IM data have been used with various computational methods, they have not yet been utilized to predict monomeric protein ...

Here, we present native liquid extraction surface analysis (LESA) mass spectrometry imaging of proteins and protein complexes from mouse brain and liver tissue. Intact proteins were detected in characteristically low charge states, indicating that the proteins remain folded. In brain, abundant proteins ...
Both peptide-centric (bottom-up) and protein-centric (top-down) approaches to protein characterization have been adopted and are now routinely applied.Mass spectrometry has also been pivotal to the development and wide application of proteomics: i.e. the large-scale identification of the proteins ...
MS Bioworks provides highly accurate data for biological research via protein mass spectrometry and proteomics using a state-of-the-art laboratory.
including proteomics. The development of high-throughput and quantitative MS proteomics workflows within the last two decades has expanded the scope of what we know about protein structure, function, modification and global protein d...
