Alcian yellow as a fluorescent dye

Acta Histochemica, 1989
Fluorescence characteristics of the cationic dye Alcian yellow are described. Under ultraviolet excitation, the chromatin and basophilic cytoplasm from cell smears show a blue-white emission, which depends on the presence of nucleic acids. Glycosaminoglycans-containing structures (mast cell granules, cartilage matrix) appear brightly fluorescent.

Depolarization of the Fluorescence of Proteins labelled with Various Fluorescent Dyes [PDF]

open access: possibleNature, 1960
THE technique by which measurements of the depolarization of fluorescence of protein conjugates is used for investigating rotational relaxation has been applied mainly with the fluorescent dye, 1-dimethylamino-naphthalene-5-sulphonic acid (I) 1,2.

Fluorescent dyes

Review of Progress in Coloration and Related Topics, 1993
: This chapter reviews the chemistry and application technology of fluorescent dyes as applied to textiles. Following a brief review of the historical background, the physical principles underlying fluorescence are presented. The molecular structures of fluorescent dyes for textile applications are illustrated and discussed in terms of general ...

Lucifer dyes—highly fluorescent dyes for biological tracing [PDF]

open access: possibleNature, 1981
Lucifer dyes are intensity fluorescent 4-aminonaphthalimides which are readily visible in living cells at concentrations and levels of illumination at which they are nontoxic. Because of their low molecular weight they frequently pass from one cell to another; this widespread phenomenon, termed dye-coupling, is thought to reveal functional ...

Depolarisation of the fluorescence of proteins labelled with various fluorescent dyes

Biochimica et Biophysica Acta, 1961
Abstract 1. 1. The behaviour of a series of fluorescent dyestuffs, when conjugated to protein molecules has been examined. 2. 2. Assuming the relaxation time for bovine serum albumin, the excited lifetimes of the dyestuffs vary from 0.25 to 9·10 −8 sec.

The metachromasia of fluorescence of acridine dyes

Histochemie, 1962
1. Fluorescence- and absorption spectra of a number of acridine dyes were measured at several concentrations, in different solvents and at various pH and temperatures. 2. In aqueous solutions metachromatic shifts are visible with all dyes — except acridine-yellow — with increasing concentrations, even when the dye is present as di- or trivalent ions in

Enhanced Dye Fluorescence in Novel Dye–ZnO Nanocomposites

Advanced Functional Materials, 2010
AbstractNew fluorescein isothiocyanate/fluorescein/rhodamine B‐doped ZnO composite nanostructures including tripods, tubes, and rods with tuned sizes have been designed and synthesized to greatly enhance the dye fluorescence up to ∼90 fold. The great fluorescence enhancement mainly arises from the interaction between Zn2+ ions in the ZnO matrix and the

Fiberized fluorescent dye microtubes

SPIE Proceedings, 2013
In the present work we study the effect of the length of fluorescent dye-filled micro-capillaries on the fluorescence spectra. Two types of micro-capillaries have been studied: a 100 μm inner diameter fused silica capillary with a transparent coating and one of the holes of a fiber optic glass ferrule with 125 μm inner diameter. The tubes were filled
