Biotinylation reagents and kits to chemically tag and label antibodies, proteins and peptides with biotin at particular amino acid functional groups to create labeled antibody or other probes for streptavidin affinity binding, purification and detection.
Selection Guides – Choose a product for your biotinylation experiment:
Labeling reagents and kits to specifically biotinylate antibodies and other proteins or peptides with biotin labels at primary amines (lysine and N-terminus), the most abundant reactive group on the surface of proteins, for streptavidin detection.
Hydrazide-activated labeling reagents to biotinylate polyclonal antibodies and other glycoproteins with biotin labels at oxidized sugar and carbohydrate groups for streptavidin detection and purification.
Amine-modified biotin labels to specifically biotinylate peptides (C-terminus), carboxyl-coated surfaces and other carboxylic acid groups using the carbodiimide crosslinker EDC (EDAC).
Azido, psoralen and other photo-reactive (UV-activated) biotin labeling compounds to biotinylate proteins, nucleic acids or organic molecules for use as molecular probes with streptavidin conjugates.
Maleimide, iodoacetyl and cleavable pyridyldithiol activated biotin labeling reagents and kits to specifically biotinylate antibodies and other proteins or peptides at sulfhydryl groups, such as reduced free thiols on cysteine residues.
Simple and accurate HABA dye assay and fluorescent detection kits to measure the amount of biotin attached to proteins or other biomolecules following biotinylation; determine the molar ratio of biotin to labeled antibody molecule.
