Biotin extinction coefficient
Webabsorptivity or extinction coefficient at the wavelength (λ). For HABA/avidin samples at 500nm, pH 7.0 extinction coefficient is equal to 34,000 M-1. cm-1. b. is the cell path length expressed in centimeters (cm). A 10mm square cuvette has a path length of 1.0cm. Using the recommended microplate format volumes, the path length is typically 0 ... WebThe water-soluble biotin-XX sulfosuccinimidyl ester (biotin-XX, SSE) provided in this kit reacts efficiently with pri-mary amines of proteins to form stable biotin-protein conjugates. After conjugation the biotin moieties are separated from the pro-tein by a 14-atom spacer consisting of two aminohexanoic acid chains (“XX”).
