Depolarization of the Fluorescence of Proteins labelled with Various Fluorescent Dyes

Nature, 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.

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.

Lucifer dyes—highly fluorescent dyes for biological tracing

Nature, 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 ...

Axially Chiral Bichromophoric Fluorescent Dyes

The Journal of Organic Chemistry, 2011
A new life for Kurt Mislow's authentic amines: Diaminobiphenyls were applied as the framework materials for the synthesis of axially chiral bichromophoric systems with strong CD and CPL effects.

Contact urticaria caused by a fluorescent dye

Australasian Journal of Dermatology, 2010
ABSTRACTA 28‐year‐old man developed urticaria while he was working in the garage. We suspected contact urticaria, which can be caused by some products used in his field, and we carried out a prick test using his work gloves and shoes. His gloves were orange and black in colour, his shoes were black and white in colour, and the materials they were made ...

Ballistic Labeling with Fluorescent Dyes and Indicators

Current Protocols in Neuroscience, 2008
AbstractNeuronal cell labeling is fundamental to investigations of the nervous system. Labeling of cells in live or fixed tissue with dyes or ion indicators using ballistic approaches has recently been developed for the study of neuronal architecture and function. In this approach, dye‐coated particles are propelled into cells by a pulse of pressurized

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.

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 ...
