Journal of the Franklin Institute, 1927
Suitable methods for the determination of eosin and ethyl eosin in samples of the latter dye are described. They depend upon the possibility of precipitating the color acid and measuring the same gravimetrically. What proportion of the dye is actually ethyl eosin and what proportion is eosin Y can be determined by making use of the great difference in ...

Histochemie, 1973
The mechanism of gelatine staining with four selected fluorone derivative dyes (eosin y, ethyl eosin, methyl eosin, uranin) was investigated. Gelatine films were stained in dye-buffer-ethanol solutions at varying pH and in the presence of NaCl and urea. Dye binding was recorded spectrophotometrically. Ionization constants of auxochromic phenolic groups

PHOTODYNAMIC INACTIVATION OF LYSOZYME BY EOSIN
Photochemistry and Photobiology, 1973Abstract— It has been demonstrated that singlet oxygen is the major oxidizing entity in the photo‐dynamic inactivation of hen egg white lysozyme by eosin, using D2O to enhance the solvent‐induced decay lifetime, and azide ion as a specific scavenger.

The Effect of pH on Staining by Eosins
Stain Technology, 1955The effect of pH on staining by 7 dyes of the eosin group was studied by means of specimens fixed 12-18 hr in Gilson's, in Petrunkewitsch's, or in Zenker's fluids, respectively. Sections were soaked in water or alcohol, depending upon the stain solvent, adjusted in 31 equal steps from pH 4.0 to 10.0 before being stained in similarly adjusted dye ...

Mit den in jedem Labor vorratigen fertigen Farblosungen nach May-Grunwald oder Giemsa lassen sich Epon-, Araldit-, und Methacrylat-schnitte farben. Collan [1] findet, das sich Eponschnitte mit der Losung nach May-Grunwald in 15–30 min, mit dem Farbgemisch nach Giemsa in 10–20 min anfarben, beides bei Raumtemperatur.
