Neutral Red as a Lipid Fluorochrome
Stain Technology, 1970Aqueous 0.1% neutral red adjusted to pH 6.5, or mixed 1:1 with seawater, produced conspicuous fluorescence in plant and animal fats while acting as a conventional stain for acidic groups including volutin. The water-soluble, nonfluorescent dye predominating in acid solutions became deprotonized, lipophilic and fluorescent under neutral and alkaline ...

A Dual Fluorochrome Probe for Imaging Proteases
Bioconjugate Chemistry, 2004Near-infrared fluorescence (NIRF) optical probes have been able to provide a noninvasive assessment of enzyme activity for a number of different enzymes and types of pathology. Here we describe a dual fluorochrome enzyme-activatable probe featuring one NIRF fluorochrome that is activated by protease activity and a second fluorochrome that is protease ...

Fluorescence and fluorochromes
2000Abstract Fluorescence occurs when a molecule excited by light of one wavelength returns to the unexcited (ground) state by emitting light of a longer wavelength. The exciting and emitted light, being of different wavelengths, can be separated from one another using optical filters.

Heterochromatin recognition with fluorochromes
Chromosoma, 1970Some types of acridine derivative and especially Quinacrine dihydrochloride and its mustard may be successfully used as chromosome marker and to investigate the chemical differentiation of euchromatin and heterochromatin. — There are at least four main types of heterochromatin, showing all possible combinations of positive and negative cold effect ...

Polyene dyes and fluorochromes
2020Polyene dyes and fluorochromes contain linked methine groups forming a chain of trans-oriented conjugated carbon-carbon double bonds, as shown below in structure a. In the naturally occurring carotenoids these are lipophilic alicyclic or aliphatic groups (as in lycopene) or hydrophilic groups such as hydroxy or carboxyl (as in crocetin).

Fluorochromes and Fluorescence
2007To facilitate flow cytometry, there is a need for cells to be labeled with fluorochromes. However, because of the spectral properties of fluorochromes, the fluorescence associated with one fluorochrome may be detected by more than one detector, producing spectral overlap which requires compensation.

Visualization of chloroplast DNA with two fluorochromes
Experimental Cell Research, 1978Abstract A simple and rapid procedure is described in which the fluorochromes 33258 Hoechst and DAPI were used to stain algal cells. Three types of extranuclear fluorescent particles could be distinguished. Type 1 particles, which fluoresced with an orange color, were polyphosphate granules.

The Use of Fluorochromes for the Detection of Malaria Parasites
The American Journal of Tropical Medicine and Hygiene, 1970Abstract A fluorochrome method is described for the rapid detection of low densities of malaria parasites in peripheral blood films. The method depends on the high-intensity fluorescence of malaria parasites in thick blood films stained with acridine orange.
