Solgel transition in dye fluorescence measurements
Applied Optics, 1997The 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

Aptamers Switch on Fluorescence of Triphenylmethane Dyes
Journal of the American Chemical Society, 2003MG and SRB aptamers, which are short RNA sequences originally selected only for binding to malachite green or sulforhodamine B, can greatly enhance the fluorescence of normally nonfluorescent triphenylmethane dyes. MG aptamer enhances the quantum yields of malachite green (MG) and a novel rigidized derivative, indolinyl malachite green (IMG) by >2000 ...

Labeling Bacterial Flagella with Fluorescent Dyes
2018We 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.

Fast Fluorescence Measurements in Dyes
Journal of Applied Physics, 1968Excited singlet lifetimes of ∼2 nsec for cryptocyanine and ∼6 nsec for chloroaluminum phthalocyanine have been measured directly from fluorescence. The fast excitation source is a mode-locked ruby laser. A model is proposed to explain these and other relaxation measurements compatible with the observed fluorescent efficiencies of the dyes.

Intracellular Staining with Fluorescent Dyes
1980Classically, neuroanatomy has been studied using a variety of tissue-applied stains. Such stains vary in their ability to highlight cells. At one end of the spectrum most of the neurons present are stained to reveal the gross architecture of the brain.

Labeling Mitochondria with Fluorescent Dyes for Imaging
Cold Spring Harbor Protocols, 2009INTRODUCTIONThe eukaryotic cell has evolved to compartmentalize its functions and transport various metabolites among cellular compartments. Therefore, it is important to study cellular organization and structure/function relationships. The mitochondrion is a double-membraned organelle that is important in various metabolic processes, including ...
