Biotin is a water-soluble vitamin, and its non-covalent interaction with streptavidin or avidin is the strongest known protein-ligand interaction, with an affinity constant (K) of 10^15 mol/L. This binding is exceptionally tight, enduring extreme conditions such as variations in pH, temperature, exposure to organic solvents, and denaturants. Biotin-linkers, which are complexes formed by attaching biotin to various linkers, are designed to meet application needs such as probe construction, affinity purification, and drug delivery.
