MS identification has long been used for PAGE-separated protein bands, but global and systematic quantitation utilizing MS after PAGE has remained rare and not been reported for native PAGE. Here we reported on a new method combining native PAGE, whole-gel slicing and quantitative LC-MS/MS aiming c...
Host cell protein (HCP) impurities are considered a critical quality attribute of biopharmaceuticals because of their potential to compromise safety and efficacy, and LC/MS-based analytical methods have been developed to identify and quantify individual proteins instead of employing enzyme-linked im...
Plasma samples from adult male rats were separated by nondenaturing micro 2DE and a representative gel was selected, on which a total of 136 CBB-stained spots were numbered and subjected to in-gel digestion and label-free quantitative LC-MSE (MS/MS in data-independent acquisition mode). The analysi...
Soluble proteins of human bronchial smooth muscle cells (HBSMC) were separated by nondenaturing micro 2DE and a 30 mm X 40 mm area of the CBB-stained slab gel (1.0 mm thick) was cut into 1.1 mm X 1.1 mm squares, then the proteins in the 972 gel pieces (squares) were applied to quantitative LC-MS/MS....
This ProteomeXchange dataset contains native mass spectrometry and intact-protein mass spectrometry data generated in support of the manuscript “A labile sulfur ligand in a three-cysteine-coordinated [2Fe-2S] cluster mediates sulfide sensing in NreB”. The dataset includes intact-protein MS measureme...
