Crosslinking Reagents
Thermo Scientific™ SM(PEG)4 (PEGylated SMCC crosslinker)
Crosslink amines to sulfhydryls with these crosslinkers containing NHS-ester and maleimide groups at ends of water-soluble polyethylene glycol spacer arms (17.6 to 95.2A).
Thermo Scientific™ BS3-d0 (bis(sulfosuccinimidyl) suberate-d0)
Crosslink amines to amines using these heavy (deuterated) and light matched pairs of an 11.4A, NHS-ester crosslinker for mass spectrometry analysis of protein interactions.
Invitrogen™ Succinimidyl 3-(2-Pyridyldithio)Propionate (SPDP)
The succinimidyl ester chemically reacts with primary amines and after mild reduction of the dithiol, it can react form a disulfide with other thiols.
Thermo Scientific™ BS(PEG)9
Crosslink amines to amines with these long (21.7A and 35.8A) crosslinkers composed of NHS-ester groups and 5-unit or 9-unit PEG spacer arms that enhance protein solubility.
Thermo Scientific™ SM(PEG)8 (PEGylated, long-chain SMCC crosslinker)
Crosslink amines to sulfhydryls with these crosslinkers containing NHS-ester and maleimide groups at ends of water-soluble polyethylene glycol spacer arms (17.6 to 95.2A).
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™ MPBH (4-(4-N-maleimidophenyl)butyric acid hydrazide)
Crosslink sulfhydryls to periodate-treated glycoprotein sugars with this long (17.9A) 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™ PDPH (3-(2-pyridyldithio)propionyl hydrazide)
Crosslink sulfhydryls to periodate-treated glycoprotein sugars via cleavable disulfide bonds using this short crosslinker containing pyridyldithiol and hydrazide groups.
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).
Thermo Scientific™ Sulfo-SDA (Sulfo-NHS-Diazirine) (sulfosuccinimidyl 4,4'-azipentanoate)
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).
Thermo Scientific™ SIAB (succinimidyl (4-iodoacetyl)aminobenzoate)
Crosslink amines to sulfhydryls with this mid-length crosslinker composed of NHS-ester and iodoacetyl (haloacetyl) groups at ends of a 9-atom (10.6A) aminobenzoate spacer arm.
Thermo Scientific™ SBAP (succinimidyl 3-(bromoacetamido)propionate)
Crosslink amines to sulfhydryls with this short crosslinker composed of NHS-ester and bromoacetyl (haloacetyl) groups at ends of a 7-atom (6.2A) spacer arm.
Thermo Scientific™ Sulfo-SMPB (sulfosuccinimidyl 4-(N-maleimidophenyl)butyrate)
Crosslink amines to sulfhydryls with this mid-length, water-soluble crosslinker composed of sulfo-NHS-ester and maleimide groups at ends of an aromatic, 10-atom spacer arm.
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.
