Immobilize or conjugate proteins using 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (CAS 25952-53-8), a water-soluble, carboxyl-to-amine crosslinker.
Crosslink amines to amines with disuccinimidyl tartrate, composed of NHS-ester groups and a diol-containing spacer arm (6.4A) that is periodate-cleavable.
Crosslink amines to amines with dithiobispropionimidate; composed of imidoester groups at either end of a reducible (cleavable) disulfide-containing spacer arm.
Diazirine analogs of leucine and methionine to express proteins in cell culture that will crosslink their protein interactors upon UV-light activation in vivo.
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.
Chemically conjugate any two purified proteins (antibodies, enzymes, carriers, etc.) using sulfo-SMCC crosslinker, a complete kit with modification reagents and buffers.
Prepare amine-reactive NHS-ester crosslinkers or enhance carbodiimide (EDC) conjugation for peptides or proteins using N-hydroxysuccinimide, CAS 6066-82-6.
Long (25.7A) amine-to-sulfhydryl crosslinker; NHS-ester and pyridyldithiol groups at ends of 4-unit polyethylene glycol spacer arm; forms cleavable disulfide bonds; water-soluble.
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).
