Mass spectrometry-based quantitative chemoproteomics is widely used for the identification of protein targets as well as modified residues, however, sample preparation and data analysis remain tedious. Here, the authors develop silane-based cleavable linkers functionalized tandem mass tags as click-compatible isobaric tags, introducing the isobaric label earlier in sample preparation, achieving decreased sample preparation time, with high coverage and high-accuracy quantification.
