Aggregation of acridine orange: Crystal structure of acridine orange tetrachlorozincate 2C17H19N3·2HCl·ZnCl2·CH3COOH

Bioinorganic Chemistry, 1976
The crystal structure of the biological stain, "acridine orange," has been determined. This compound, when crystallized from ethanol, is shown to be a zinc chloride double salt of acridine orange, containing, in addition, acetic acid of crystallization. These additional components are residuals from the method of preparation of acridine orange.

Acridine orange staining of Pneumocystis carinii

Journal of Clinical Microbiology, 1982
Acridine orange was used to stain smears of mouse lung which contained cyst and trophozoite forms of Pneumocystis carinii. Trophozoite forms stained yellow to orange; however, cyst forms did not stain. Acridine orange is a rapid and sensitive method for demonstrating trophozoites of P. carinii in mouse lung tissue.

Acridine Orange Fluorescence in Paraffin Sections

Stain Technology, 1962
The technique of staining with acridine orange for fluorescence microscopy of fresh animal and plant cells, chiefly for the detection of ribonucleic acid in the cytoplasm, was brought to a high degree of perfection by Schummelfeder (1950) and has been developed further by Bertalanffy and Bickis (1956).

Excited state characteristics of acridine dyes: acriflavine and acridine orange

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2003
The magnitude of the Stokes shift (frequency shifts in absorption and fluorescence spectra) is observed on changing the solvents and further has been used to calculate experimentally the dipole moments (ground state and excited state) of acriflavine and acridine orange dye molecules. Theoretically, dipole moments are calculated using PM 3 Model.

Acridine Orange in Gynecologic Cancer

Acta Obstetricia et Gynecologica Scandinavica, 1972
With the ultimate purpose of evaluating the accuracy and specificity of the fluorescence of acridine orange stained cells or tissues as a sign of malignancy, this compound and its binding to stain receptors have been studied with biophysical methods. The present paper describes the identification of the lines in the proton magnetic resonance spectrum ...

Sequential Q- and acridine orange-marker technique

Humangenetik, 1975
A standardized Q- and acridine orange (AO)-fluorescence dual marker technique was described. It involved preservation of unstained chromosome slides in a vacuum desiccator up to 18 months, Q-staining, destaining, and treatment in Hanks' solution, pH 5.1, at 85 degrees C for 13 min, and acridine orange staining.

Acridine Orange Fluorescent Stain for Fungi

Archives of Dermatology, 1961
Introduction Acridine orange has been used for some time as a fluorescent stain for nucleoproteins and for tissue mucopolysaccharides. 6 It has also found use as a vital stain for blood parasites. 8 By accident it was found that the technique of Hicks and Matthaei for the fluorescent staining of mucin 4 would also stain fungi in tissue sections ...
