DHSO Crosslinker is a homobifunctional, acidic residue-targeting, sulfoxide-containing crosslinker for analysis of protein-protein interactions (PPIs) through crosslinking mass spectrometry (XL-MS). DHSO possesses two hydrazide-reactive groups for targeting aspartic acid (Asp) and glutamic acid (Glu) and two symmetrical C-S cleavable bonds adjacent to the central sulfoxide. While former amine-reactive reagents react with lysine (Lys) residues in proximity to the PPI, targeting acidic residues provides further opportunity to characterize protein interaction surfaces at which Asp and Glu are often prevalent. Additionally, the 12.4 Å spacer yields tagged peptides post-cleavage for unambiguous identification by collision-induced dissociation in tandem MS. DHSO Crosslinker provides complementary data to Lys-targeting reagents and will find wide utility in the elucidation of PPIs, study of proteins that function as complexes, quantification of structural dynamics, and quest for targeting "undruggable" protein targets.

Cross-linking mass spectrometry (XL-MS) has become a powerful strategy for defining protein-protein interactions and elucidating architectures of large protein complexes. However, one of the inherent challenges in MS analysis of cross-linked peptides is their unambiguous identification. To facilitate this process
