Crosslinking Reagents
Crosslinking Reagents
Thermo Scientific™ Pierce™ EDC, No-Weigh™ Format
Immobilize or conjugate proteins using 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (CAS 25952-53-8), a water-soluble, carboxyl-to-amine crosslinker.
MilliporeSigma™ Calbiochem™ SMCC, Water-Soluble
Used for coupling enzymes to antibodies.
MilliporeSigma™ Calbiochem™ SATA
Reacts with primary amines to add protected sulfhydryl groups.
MilliporeSigma™ Calbiochem™ THIOLYTE™ Monobromobimane Reagent, Fluorescent Labeling Compound
Used to label E.coli thioredoxin.
Thermo Scientific™ LC-SPDP (succinimidyl 6-(3(2-pyridyldithio)propionamido)hexanoate)
Crosslink amines to sulfhydryls with this crosslinker composed of NHS-ester and pyridyldithiol groups at ends of 10-atom (15.7A) spacer arm.
Thermo Scientific™ KMUH (N-κ-maleimidoundecanoic acid hydrazide)
Crosslink sulfhydryls to periodate-treated glycoprotein sugars with this long (19.0A) crosslinker containing maleimide and hydrazide groups.
Thermo Scientific™ AMAS (N-α-maleimidoacet-oxysuccinimide ester)
Crosslink amines to sulfhydryls with this very short crosslinker composed of NHS-ester and maleimide groups at ends of an aliphatic, 4-atom (4.4A) spacer arm.
Thermo Scientific™ EMCS (N-ε-malemidocaproyl-oxysuccinimide ester)
Crosslink amines to sulfhydryls with this mid-length crosslinker composed of NHS-ester and maleimide groups at ends of an aliphatic, 8-atom (9.4A) spacer arm.
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™ SIA (succinimidyl iodoacetate)
Crosslink amines to sulfhydryls with this very short crosslinker composed of NHS-ester and iodoacetyl (haloacetyl) groups at ends of a 3-atom (1.5A) spacer arm.
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™ 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.

Thermo Scientific™ SPB (succinimidyl-[4-(psoralen-8-yloxy)]-butyrate)
Crosslink amines to DNA with this crosslinker composed of NHS-ester and psoralen reactive groups; conjugates to DNA via light-activated intercalation next to pyrimidine bases.
Thermo Scientific™ Pierce™ Controlled Protein-Protein Crosslinking Kit
Chemically conjugate any two purified proteins (antibodies, enzymes, carriers, etc.) using sulfo-SMCC crosslinker, a complete kit with modification reagents and buffers.
Thermo Scientific™ SDAD (NHS-SS-Diazirine) (succinimidyl 2-((4,4'-azipentanamido)ethyl)-1,3'-dithiopropionate)
Very short to mid-length (3.9 to 13.5A), amine-to-anything crosslinkers; NHS-ester and diazirine reactive groups; photoactivate with UV light (Amax 330 to 370nm).
