Crosslinking Reagents
Thermo Scientific™ BMPH (N-β-maleimidopropionic acid hydrazide)
Crosslink sulfhydryls to periodate-treated glycoprotein sugars with this short (8.1A) crosslinker containing maleimide and hydrazide groups.
Thermo Scientific™ DTME (dithiobismaleimidoethane)
Crosslink sulfhydryls to sulfhydryls (cysteine residues) with this long, cleavable crosslinker composed of maleimide groups and 11-atom (13.3A) disulfide spacer arm.
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™ L-Photo-Methionine
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™ PEG12-SPDP (PEGylated, long-chain SPDP crosslinker)
Very long (54.1A) amine-to-sulfhydryl crosslinker; NHS-ester and pyridyldithiol groups at ends of 12-unit polyethylene glycol spacer arm; forms cleavable disulfide bonds; water-soluble.
Thermo Scientific™ PMPI (p-maleimidophenyl isocyanate)
Short (8.7A) hydroxyl-to-sulfhydryl crosslinker; isocyanate and maleimide groups; label -OH by urethane bonds for conjugation to cysteines by thioether bonds.
Thermo Scientific™ NHS-Azide
Activated azido compounds to derivatize proteins or amine surfaces for selective conjugation, detection or purification by phosphine-modified probes.
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™ SMPH (Succinimidyl 6-((beta-maleimidopropionamido)hexanoate))
Crosslink amines to sulfhydryls with this long crosslinker composed of NHS-ester and maleimide groups at ends of an aliphatic, 12-atom (14.2A) spacer arm.
