Biotin Acid

Dyes, Labeling Reagents and Kits | Biotin and Digoxigenin Labeling Reagents: Biotin Acid

Biotin Acid is the carboxylic acid form of biotin used as a foundational building block in bioconjugation chemistry. It serves as a precursor for synthesizing biotinylated compounds by enabling covalent attachment to amines, alcohols, or other functional groups through activation (e.g., as an NHS ester), facilitating incorporation into detection or affinity systems involving avidin or streptavidin.
