Steptavidin, a bacterial protein isolated from Streptomyces avidinii, is similar to egg-white avidin in its ability to bind biotin, and has been used as a replacement for egg-white avidin because of its more favorable chemical properties. Conjugates of streptavidin are recommended for use with…

HOOK™-Iodoacetyl-LC-Biotin reacts with protein free sulhydryl groups. Sulfhydryl reactive reagents are more specific and react only with free sulfhydryl residues (-SH or thiol groups). The side chain of the amino acid cysteine is the most common source of free sulfhydryl groups. If free…

HOOK™-Biotin-PEG₂-Amine reacts with protein carboxyl groups in the presence of the heterobifunctional cross-linker EDC. HOOK™-Biotin-Pentylamine, HOOK™-Biotin-PEG₂-Amine and HOOK™-Biotin-PEG₃-Amine are water soluble, due to its polyethylene…

HOOK™-Sulfo-NHS-LC-Biotin reacts with protein primary amines. Amines, lysine ε-amines and N-terminal α-amines, are the most abundant group in protein molecules and represent the most common target for biotinylation. For example, BSA contains 59 primary amines, of which up to 35…
