Fluorescein Derivatives in Intravital Fluorescence Imaging
Intravital fluorescence microscopy enables the direct imaging of fluorophores in vivo and advanced techniques such as fluorescence lifetime imaging (FLIM) enable the simultaneous detection of multiple fluorophores. Consequently, it is now possible to record distribution and metabolism of a chemical in vivo and to optimise the delivery of fluorophores in vivo. Recent clinical applications with f...
متن کاملActivation and inhibition of ATP-sensitive K+ channels by fluorescein derivatives.
Fluorescein derivatives are known to bind to nucleotide-binding sites on transport ATPases. In this study, they have been used as ligands to nucleotide-binding sites on ATP-sensitive K+ channels in insulinoma cells. Their effect on channel activity has been studied using 86Rb+ efflux and patch-clamp techniques. Fluorescein derivatives have two opposite effects. First, like ATP, they can inhibit...
متن کاملThe invalidity of the photo-induced electron transfer mechanism for fluorescein derivatives.
The ground and excited state geometries, the excitation and emission energies for a series of fluorescein derivatives in aqueous solutions have been investigated using time-dependent density functional theory (TD-DFT) with B3LYP and a long-range corrected CAM-B3LYP functional. The RI-CC2 method was employed to confirm the CAM-B3LYP results. As far as we know, the excited state geometries for a ...
متن کاملSpectral properties and structure of fluorescein and its alkyl derivatives in micelles
The absorption and fluorescence spectra, the fluorescence quantum yields and lifetimes of fluorescein and three series of alkylated fluorescein, namely, esters, ethers and ester ethers of fluorescein in SDS, CTAB and TX-100 micelles, were investigated. The interactions between the dyes and micelles, and the existing structure forms of the dyes in micelles were also studied. All alkylated fluore...
متن کاملFundus photography and fluorescein angiography Fluorescein angiography
Fluorescein angiography is a clinical diagnostic test procedure in which rapid-sequence photography is performed after intravenous injection of sodium fluorescein. The procedure allows the documentation of the retinal circulation. Of equal importance is the ability of the angiogram to outline the entire retinal vascular bed. Previous clinical methods of examination of the fundus enabled the phy...
