WebFluorescein (FITC) Fluorescence SpectraViewer. Fluorescein derivatives are the most common fluorescent reagents for biological research because of their high absorptivity, excellent fluorescence quantum yield, and good water solubility. Fluorescein-based … WebWe present absolute two-photon absorption (2PA) spectra of 15 commercial organic dyes covering an extended range of excitation wavelengths, 550–1600 nm. The 2PA is measured with an estimated accuracy ±10% using a femtosecond fluorescence excitation method. The data are corrected for the variations of the pulse duration and the beam profile with the …
WebThe pH-dependent absorption spectra of fluorescein (Figure 20.2.2) clearly show the blue shift and decreased absorptivity indicative of the formation of protonated species. However, the fluorescence emission spectrum of most fluorescein derivatives, even in acidic solution, is dominated by the dianion, with only small contributions from the ... WebAlexa Fluor 488 (Amax 493 nm, Emax 519 nm) has absorption and emission spectra comparable to Fluorescein (FITC), but are much brighter, far more photostable and less sensitive to pH changes between pH 4 and 10. Alexa Fluor 488 conjugates are compatible with common fluorescein equipment, settings, or filters and are ideally suitable for all ...

In addition, an ...
WebFluorescein isothiocyanate ( FITC) is a derivative of fluorescein used in wide-ranging applications [1] [2] including flow cytometry. First described in 1942, [3] FITC is the original fluorescein molecule functionalized with an isothiocyanate reactive group (−N=C=S), replacing a hydrogen atom on the bottom ring of the structure.
