Fluorometry - an overview ScienceDirect Topics

WebFluorometric detection typically relies on the use of an antibody that has been labeled with a fluorophore. Once the antibody has bound to its target, a light source is used to excite the fluorophore, which then produces a transient light emission as it returns to its ground state. WebDetection principle Production of o-nitrophenol and galactose by o-nitrophenol-β-D-galactoside (ONPG) catalyzed by sodium dependent β-D-galactosidase. The amount of o-nitrophenol is directly proportional to the concentration of sodium ion in the sample.
