Crosslinking Reagents
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™ SM(PEG)2 (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™ NHS-PEG4-Azide
Activated azido compounds to derivatize proteins or amine surfaces for selective conjugation, detection or purification by phosphine-modified probes.
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™ BM(PEG)2 (1,8-bismaleimido-diethyleneglycol)
Crosslink sulfhydryls to sulfhydryls (cysteine residues) with this long, pegylated, water-soluble crosslinker composed of maleimide groups and 2-unit (14.7A) PEG spacer arm.
Thermo Scientific™ BM(PEG)3 (1,11-bismaleimido-triethyleneglycol)
Crosslink sulfhydryls to sulfhydryls (cysteine residues) with this long, pegylated, water-soluble crosslinker composed of maleimide groups and 3-unit (17.8A) PEG spacer arm.
Thermo Scientific Pierce™ Pierce™ SM(PEG)12, No-Weigh™ Format
Thermo Scientific™ Pierce™ SM(PEG)12 is hetero-bifunctional crosslinker with N-hydroxysuccinimide (NHS) ester and maleimide groups that allow covalent conjugation of amine- and sulfhydryl-containing molecules.
Thermo Scientific™ EZ-Link™ Maleimide-PEG4-DBCO
A sulfhydryl reactive heterobifunctional crosslinker which contains a dibenzylcyclooctyne (DBCO) group for copper-free click chemistry applications. The thiol/sulfhdryl reactive maleimide can be used to label a variety of thiol containing moieties such as free cystines in proteins, peptides, or other (bio)molecules.
Thermo Scientific™ Mass Spectrometry Compatible Crosslinkers
Improve mass spectrometry detection of crosslinked proteins and interactions with DSPP and TBDSPP heterotrifunctional crosslinkers.
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™ 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™ MBS (m-maleimidobenzoyl-N-hydroxysuccinimide ester)
Crosslink amines to sulfhydryls with this short crosslinker composed of NHS-ester and maleimide groups at ends of an aromatic, 6-atom (7.3A) spacer arm.
Thermo Scientific™ Pierce™ Premium Grade DSP (dithiobis(succinimidyl propionate))
Optimize applications where product integrity and risk minimization are paramount with our highest quality formulation of this popular amine-reactive, cleavable crosslinker.
Thermo Scientific™ DTBP (Wang and Richard's Reagent)
Crosslink amines to amines with dithiobispropionimidate; composed of imidoester groups at either end of a reducible (cleavable) disulfide-containing spacer arm.
