Cross linkers are used for the identification of near-neighbour protein relationships and ligand-receptor interactions. Homobifunctional, amine-reactive NHS esters or imidates, and heterobifunctional, amine-reactive, photoactivatable phenyl azides are the most commonly used crosslinkers for these applications.

Supplier: Merck Millipore (Oncogene)

Biotin-NHS reacts with primary amines to biotinylate proteins under mild conditions. Since it is water-soluble, this compound can be used to biotinylate cell-surface proteins and proteins that are sensitive to organic solvents.

Supplier: Thermo Fisher Scientific

Maleimide-Activated Streptavidin is for directly preparing streptavidin-protein conjugates with proteins, peptides and other molecules that contain a free sulphhydryl (-SH) group. Streptavidin has been maleimide-activated using Sulpho-SMCC, a heterobifunctional crosslinker that contains an N-hydroxysuccinimide ester and a maleimide group. The activated streptavidin presents an available maleimide group that reacts with sulphhydryl-containing molecules.

The HOOK™ Peptide Coupling kits allow researchers to attach peptides to a carrier protein of choice using either primary amines or sulfhydryls in their peptide. The HOOK™ Peptide Coupling kits can be supplied with or without carrier proteins.

Supplier: G-Biosciences

HOOK™ Biotin Reagent that conjugates to proteins through amines, sulfhydryls, carboxyls or carbohydrates. The amine and sulfhydryl coupling HOOK™ Biotin Reagents couple directly to the protein through their reactive groups, however the carboxyl coupling HOOK™ Biotin Reagents require a carbodiimide crosslinker and the carbohydrate coupling HOOK™ Biotin Reagents require carbohydrate oxidation before coupling.
