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

Endocytosis Assays Using Cleavable Fluorescent Dyes

2022
Endocytosis mediates the entry of surface and extracellular cargoes into the cell. In this chapter, we describe assays to quantitively measure the endocytosis of both soluble and transmembrane cargo proteins, taking advantage of cleavable fluorescent dyes labeling cargo proteins or antibodies recognizing cargo proteins.

Fluorescent Voltage-Sensitive Dyes

Journal of Clinical Neurophysiology, 1988
Voltage-sensitive dyes are a means to optically monitor changes in membrane potential. Their application in research has grown steadily over the last two decades as better dyes have been developed. The techniques presently in use are providing unique information about biologic systems from bacteria to the functional organization of primate occipital ...

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.

Solgel transition in dye fluorescence measurements

Applied Optics, 1997
The results of fluorescence quenching measurements, obtained for a dye-substituted aqueous gelatin solution during the sol-gel transition, are presented. Simultaneous optical polarization rotation and fluorescence studies allow us to find the dependence of the fluorescence yield on the amount of helix created in the medium. The exact gel point has been

Labeling Bacterial Flagella with Fluorescent Dyes

2018
We describe labeling of bacteria with amino-specific or sulfhydryl-specific Alexa Fluor dyes, methods that allow visualization of flagellar filaments, even in swimming cells. Bacterial flagellar filaments are long (~10 μm), but of small diameter (~20 nm), and their rotation rates are high (>100 Hz), so visualization is difficult.
