Biotin affinity purification
WebStreptavidin / ˌ s t r ɛ p ˈ t æ v ɪ d ɪ n / is a 52 kDa protein (tetramer) purified from the bacterium Streptomyces avidinii.Streptavidin homo-tetramers have an extraordinarily high affinity for biotin (also known as vitamin B7 or vitamin H). With a dissociation constant (K d) on the order of ≈10 −14 mol/L, the binding of biotin to streptavidin is one of the … WebPurification. The biotin tag can be used in affinity chromatography together with a column that has avidin (or streptavidin or neutravidin) bound to it, which is the natural ligand for biotin. However, harsh conditions (e.g., 6M GuHCl at pH 1.5) are needed to break the avidin/streptavidin - biotin interaction, which will most likely denature ...
