Many biological compounds present in cells, serum or other biological fluids are naturally fluorescent, and thus the use of conventional, prompt fluorophores leads to serious limitations in assay sensitivity due to the high background caused by the autofluorescence of the biological molecules to be assayed.

Supplier: Thermo Fisher Scientific

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: G-Biosciences

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.

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.
