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 strongest … WebBiotin can be dissolved in dimethylformamide (DMF) at a concentration of 1.7mg/ml; 1ml of this can then added dropwise to 5ml of sodium potassium phosphate buffered saline, pH 6.8. For cell culture purposes, either HCl or NaOH may be used to titrate biotin into solution.

Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates (e.g., NHS-coupling gives biotinylation of any primary amines in the protein). Enzymatic biotinylation results in biotinylation of a specific lysine within a certain sequence by a bacterial biotin ligase. Most chemical biotinylation reagents consist of a reactive group attache… WebDec 29, 2024 · Biotin is a B vitamin also known as vitamin H or B-7.
