Sample multiplexing-based proteomic strategies rely on fractionation to improve proteome coverage. Tandem mass tag (TMT) experiments, for example, can currently accommodate up to 18 samples with proteins spanning several orders of magnitude, thus necessitating fractionation to achieve reasonable pro...

The change in pH of the mobile phase drastically changes the retention mechanism of peptides, rendering currently available retention time prediction models useless. The aim of this study is to create a dataset of peptide retention times under basic (pH 9) HPLC conditions, allowing for the creation ...

Multidimensional peptide fractionation is widely used in proteomics to reduce the complexity of peptide mixtures prior to mass spectrometric analysis. Here, we describe the sequential use of strong cation exchange and reversed phase liquid chromatography in both basic and acidic pH buffers for separ...

This dataset contains proteomic profiles of extracellular vesicles (EVs) isolated from human multiple sclerosis (MS) white matter tissue, alongside the corresponding tissue proteome. The aim of this study is to characterize the protein cargo of MS-derived EVs compared to bulk tissue and to identify ...

Chemical cross-linking in combination with mass spectrometry (XL-MS) has emerged as a useful method for structural elucidation of proteins and protein complexes. Efficient enrichment procedures are necessary to analyze cross-linked products due to their relatively low abundance. Currently, strong ca...
