WebFeb 11, 2014 · Fluorescein and its derivatives form a family of versatile functional dyes (structures shown in Fig. 1), which have been widely used due to their excellent fluorescence and other photophysical properties [1, 2].Interests in designing and synthesizing new fluorescein derivatives are still enormous to meet needs in various … WebHigh level panels (>22 colors) can be built using cytometers capable of spectral detection or the ability to unmix a fluorescent spectrum across an array of emission detectors such as the Cytek™ Aurora or Northern Lights. Some fluorophores, like the Spark dyes, are specifically designed to be used on these cytometers. ... FITC, Alexa Fluor ...
WebFluorescent substances are excited by a range of wavelengths known as their absorption spectrum. They also emit a range of wavelengths known as their emission spectrum. Figure 12.1 illustrates the absorption and emission spectra for FITC in aqueous solution. For any fluorescent substance the two spectra will show an absorption WebThe effect of pH on the fluorescence efficiency of fluorescein is evaluated using thermal lens technique. Fluorescence efficiency increases as the sample becomes more and more alkaline. But when fluorescein is mixed with rhodamine B fluorescence quenching of fluorescein takes place with the excitation of rhodamine B.
