WebThe wavelength for the HABA assay is 500nm. There are no units for absorbance. ε is the absorptivity 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). WebFeb 19, 2009 · In this new method, biotin is derivatized by 9-anthryldiazomethane (ADAM) to an ester of fluorimetric biotin-ADAM and detected fluorimetrically at an excitation wavelength of 365 nm and emission wavelength of 412 nm (1,2,3). This is a simple chromatographic method using the affinity of avidin for biotin.
