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™ 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™ NHS (N-hydroxysuccinimide)
Prepare amine-reactive NHS-ester crosslinkers or enhance carbodiimide (EDC) conjugation for peptides or proteins using N-hydroxysuccinimide, CAS 6066-82-6.
Thermo Scientific™ DMP (dimethyl pimelimidate)
Crosslink amines to amines with dimethyl pimelimidate (CAS 58537-94-3); composed of imidoester groups and a membrane-permeable, 7-atom spacer arm.
Thermo Scientific™ SPDP (succinimidyl 3-(2-pyridyldithio)propionate)
Crosslink amines to sulfhydryls with this crosslinker composed of NHS-ester and pyridyldithiol groups on 3-atom spacer arm; forms cleavable disulfide bonds with cysteines.
Thermo Scientific™ Sulfo-LC-SPDP (sulfosuccinimidyl 6-(3'-(2-pyridyldithio)propionamido)hexanoate)
Crosslink amines to sulfhydryls with this water-soluble sulfo-NHS-ester and pyridyldithiol groups on 10-atom spacer arms to form cleavable disulfide bonds with cysteines.
Thermo Scientific™ LC-SMCC (succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxy-(6-amidocaproate))
Crosslink amines to sulfhydryls with this long crosslinker composed of NHS-ester and maleimide groups at ends of a stabilizing cyclohexane-containing, 15-atom spacer arm.
