Mechanism of quenching of fluorescein by anti-fluorescein IgG antibodies

Immunochemistry, 1977
Abstract The mechanism by which fluorescein underoges a spectral shift and its fluorescence is quenched when bound to rabbit anti-flurescyl IgG antibody, has been investigated. Visible absorption spectra of the fluorophore bound to the active site of purified antibody elicited to the two isomers of fluorescein (I and II) revealed different spectral ...

Phospha-fluorescein: a red-emissive fluorescein analogue with high photobleaching resistance.

Chemical Communications, 2016
Phospha-fluorescein (POF), a phosphine oxide-containing analogue of fluorescein, was synthesized and its photophysical properties were examined. Compared with fluorescein and sila-fluorescein, POF displayed significantly red-shifted absorption and ...

Studies on fluorescein—VIIThe fluorescence of fluorescein as a function of pH

Talanta, 1989
The relative fluorescence of fluorescein over the pH range 3-12 has been measured at 516 nm, with excitation at 489 nm. The relative fluorescence is essentially zero at pH 3, increases slowly between pH 4 and 5, rises rapidly between pH 6 and 7, reaches a maximum at pH 8, and remains constant at above pH 8.

Fluorescein as an artificial enzyme to mimic peroxidase.

Chemical Communications, 2016
Fluorescein was found to possess intrinsic peroxidase-like activity, which could catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) by H2O2 to produce a color reaction. It opens the possibility of using such small molecules as peroxidase-like

Proteolysis of fluoresceinated proteins

Molecular Immunology, 1965
Abstract Pronase digestion of fluoresceinated BSA, fluroresceinated human and rabbit γ-globulin, and fluoresceinated BSA-rabbit anti-BSA precipitate was studied both as a function of time, and when digestion was complete, by separation of the products by gel fibration on Sephadex G-100.

Free Plasma Fluorescein

Archives of Ophthalmology, 1985
To the Editor. —In our experiments with vitreous fluorophotometry, we measured levels of free plasma sodium fluorescein using a pressure dialysis technique (Amicon ultrafiltration membranes). We have made someobservations with this technique that other investigators may find helpful.

Fluorescein Derivatives as Bifunctional Molecules for the Simultaneous Inhibiting and Labeling of FTO Protein.

Journal of the American Chemical Society, 2015
The FTO protein is unequivocally reported to play a critical role in human obesity and in the regulation of cellular levels of m(6)A modification, which makes FTO a significant and worthy subject of study. Here, we identified that fluorescein derivatives

Time-resolved fluorescence properties of fluorescein and fluorescein glucuronide

Experimental Eye Research, 1989
The use of fluorescein as a tracer in the study of the blood-ocular barriers is complicated by the metabolic production of fluorescein monoglucuronide, the excitation and fluorescence spectra of which overlap with those of fluorescein. Time-resolved fluorescence measurements provide a means of detecting the two substances in a mixture.

A Supercritical Fluid-Based Process for the Production of Fluorescein-Loaded Liposomes

, 2016
Fluorescein is a synthetic dye used as a marker to monitor the absorption of liposomes into tissues, but its efficient entrapment is still challenging.
