Application
Azide-A-DSBSO (azide-tagged, acid-cleavable disuccinimidyl bissulfoxide) Crosslinker is a homobifunctional, membrane-permeable, enrichable disulfoxide-containing crosslinker for analysis of protein-protein interactions (PPIs) through crosslinking mass spectrometry (XL-MS).
Azide-A-DSBSO possesses two N-hydroxysuccinimide (NHS) ester groups for targeting amines, a ∼14 Å spacer length, two symmetrical acid-cleavable C-S bonds, and a central bioorthogonal azide tag. After reacting with lysine (Lys) residues, the azide tag permits selective enrichment of crosslinked proteins or peptides with a biotin-conjugated alkyne probe to enhance their detection. Additionally, the post-cleavage spacer yields tagged peptides for unambiguous identification by collision-induced dissociation in tandem MS.
Azide-A-DSBSO Crosslinker has mapped in vivo PPIs for target protein complexes and whole proteomes from living cells. It will also be a useful proteomics tool in the quest for targeting ″undruggable″ protein targets.

The cross-linking Mass Spectrometry (XL-MS) technique extracts structural information from protein complexes without requiring highly purified samples, crystallinity, or large amounts of material. However, there are challenges to applying the technique to protein complexes in vitro, and those challenges become
