Thermo Scientific™ Pierce™ Premium Grade Sulfo-SMCC (sulfosuccinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate)
Optimize applications where product integrity and risk minimization are paramount our highest quality formulation of this popular amine-to-sulfhydryl crosslinker.
Thermo Scientific™ BS2G-d0 (bis(sulfosuccinimidyl) glutarate-d0)
Crosslink amines to amines using these heavy (deuterated) and light matched pairs of a 7.7A, NHS-ester crosslinker for mass spectrometry analysis of protein interactions.
Thermo Scientific™ L-Photo-Leucine
Diazirine analogs of leucine and methionine to express proteins in cell culture that will crosslink their protein interactors upon UV-light activation in vivo.
Thermo Scientific™ Mass Spectrometry Cleavable Crosslinkers
Improve sensitivity of mass spectrometry detection of crosslinked proteins with MS-cleavable DSSO and DSBU heterotrifunctional crosslinkers.
Thermo Scientific™ EZ-Link™ TFP Ester-PEG12-DBCO
A heterobifunctional crosslinker that contains an amine reactive tetrafluorophenyl (TFP) and a dibenzylcyclooctyne (DBCO) with a water solubilizing long PEG12 spacer in between. Use to label any primary amine containing molecule such as a protein to biomolecule with a distantly attached DBCO group.
Thermo Scientific™ SMPH (Succinimidyl 6-((beta-maleimidopropionamido)hexanoate))
