Streptavidin (STV) is a homo-tetrameric bacterial protein known to exhibit an exceptionally high binding affinity for its ligand, the vitamin biotin ( Kd 10 -14 mol/L). Avidin, a 70 -kDa protein in egg white, has very high affinity for biotin. Prior to addition to the sample, avidin is incubated with enzyme-labeled biotin, thus forming a complex. 2After removing SSB with NaCl solution, complementary DNA was injected. Bookshelf Binding of this complex to the biotin moieties associated with secondary antibody results in a high staining intensity. Bethesda, MD 20894, Web Policies The influence of biotinylation on the ability of a computer designed protein to detect B-cells producing anti-HIV-1 2F5 antibodies. (19) STV's quaternary structure consists of four identical -barrel subunits, each composed of eight antiparallel -sheets. Since Streptavidin does not have sugar chain, less nonspecific binding occurs as compared with avidin. Methods Mol Biol. Abstract. Introduction: The Avidin-biotin interaction. APEX catalyzes the oxidation of biotin-phenol to the short-lived (<1 ms) biotin-phenoxyl radical in the presence of hydrogen peroxide, which then reacts with . A minimum of 6- to 8-M guanidine at pH 1.5 is required for inducing complete dissociation of the avidin-biotin interaction complex (Cuatrecasas and Wilchek, 1968; Bodanszky and Bodanszky, 1970).
