The main difference between fluorophore and chromophore is that fluorophore is a part of a molecule, re-emitting the absorbed photon at a longer wavelength whereas chromophore is a part of a molecule, absorbing UV or visible light to emit light in the visible region. These include the aromatic amino acids, NADH, flavins, derivatives of pyridoxyl, and chlorophyll. Looking a little bit deeper into a fluorophore we reach the chromophore, which is the part of a molecule that defines its color (s. Figure 2). Only at the exact center of focus (the node) is the intensity of the STED beam equal to zero. Auxochrome is a group of atoms which will impart a particular color when attached to a chromophore but when present alone, will fail to produce that color. Fluorophore properties affect the detection limit and the dynamic range of the method, the reliability of the readout for a particular tar-get or event, and the suitability for multiplexing, that is, Solutions for Chapter 13 Problem 12P: In a fluorescence-lifetime experiment, a very short pulse of light is used to excite a sample. Fluorofor dan kromofor adalah spesies kimia yang bertanggung jawab atas efek yang terlihat dalam senyawa. To achieve this, photons of light from an excitation source are absorbed by the fluorophore’s electrons, raising their energy level and causing them to move to an excited state. As judged by immunochemical analysis, treatment of protein with HNE in vitro can lead to the formation of the fluorescent chromophore identified in model reactions. Fluorophore Buyer’s Guide.
