WebAUR is non-fluorescent but is transformed into a fluorescent molecule by oxidation with HRP (Fruk, Rajendran, Spengler, & Niemeyer, 2007). Therefore, fluorescence intensity of the solution was monitored during the UV light irradiation. Figure 11 indicates changes in relative fluorescence unit (RFU) during intermittent UV light irradiation. The ... WebFluorescent markers become excited by specific wavelengths of light, and then emit light in a different wavelength. This makes them very valuable for scientific research in order to locate cells/proteins and even track them over time. kento hinode a whisker away
