Fluorometric assay principle

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. WebSep 21, 2015 · Fluorometric assays are a little more sensitive than colorimetric assays and they are able to detect more of an analyte than colorimetric assays. They allow for a very high reading to be measured by widening the dynamic range. Some labs will combine both techniques by using a clear bottom plate.
