Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

DSSO (disuccinimidyl sulfoxide) crosslinker is a homobifunctional, amine-targeting, sulfoxide-containing crosslinker for analysis of protein-protein interactions (PPIs) through crosslinking mass spectrometry (XL-MS). Membrane-permeable DSSO possesses two N-hydroxysuccinimide (NHS) esters for targeting Lys, a 10.1 +a spacer arm, and two symmetrical C-S cleavable bonds adjacent to the central sulfoxide. The post-cleavage spacer yields tagged peptides for unambiguous identification by collision-induced dissociation in tandem MS. DSSO Crosslinker provides complementary data to thiol-reactive and acidic residue-targeting reagents and will find wide utility in the elucidation of PPIs, study of proteins that function as complexes, quantification of structural dynamics, and the quest for targeting undruggable protein targets.Technology Spotlight: Cross-Linkers for Elucidation of Protein-Protein InteractionsDevelopment of a novel cross-linking strategy for fast and accurate identification of cross-linked peptides of protein complexesStructural dynamics of the human COP9 signalosome revealed by cross-linking mass spectrometry and integrative modelingDeveloping a Multiplexed Quantitative Cross-Linking Mass Spectrometry Platform for Comparative Structural Analysis of Protein ComplexesDevelopment of a Novel Sulfoxide-Containing MS-Cleavable Homobifunctional Cysteine-Reactive Cross-Linker for Studying Protein-Protein InteractionsDeveloping an Acidic Residue Reactive and Sulfoxide-Containing MS-Cleavable Homobifunctional Cross-Linker for Probing Protein-Protein InteractionsSubject to US Patent #9,222,943 and US Patent Application #15/275,001 of the Regents of the University of California
