Streptavidin

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

HOOK&trade-Biotin-BMMCC reacts with protein free sulhydryl groups. Sulfhydryl reactive reagents are more specific and react only with free sulfhydryl residues (-SH or thiol groups).

HOOK&trade-Biotin-Hydrazide reacts with oxidized carbohydrate side chains. Some biotin reagents do not bind directly to the protein itself but conjugate to the carbohydrate residues of glycoproteins.

HOOK&trade-Biotin-LC-Hydrazide reacts with oxidized carbohydrate side chains. Some biotin reagents do not bind directly to the protein itself but conjugate to the carbohydrate residues of glycoproteins.

HOOK&trade-Biotin-PDA reacts with protein free sulhydryl groups. Sulfhydryl reactive reagents are more specific and react only with free sulfhydryl residues (-SH or thiol groups).

HOOK&trade-Biotin-PEG₂-Amine reacts with protein carboxyl groups in the presence of the heterobifunctional cross-linker EDC. HOOK&trade-Biotin-Pentylamine, HOOK&trade-Biotin-PEG₂-Amine and

HOOK&trade-Biotin-PEG₃-Amine reacts with protein carboxyl groups in the presence of the heterobifunctional cross-linker EDC. HOOK&trade-Biotin-Pentylamine, HOOK&trade-Biotin-PEG₂-Amine and

HOOK&trade-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).

HOOK&trade NHS-Biotin reacts with protein primary amines. Amines, lysine &epsilon-amines and N-terminal &alpha-amines, are the most abundant group in protein molecules and represent the most common target for biotinylation.
