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 ...

Allergic contact dermatitis from eosin
Contact Dermatitis, 1991Before 1960, eosin sensitivity was not rare and lipstick cheilitis was very common. We report 4 patients soon in 1988 and 1989 who were sensitized to eosin from topical bacteriostatic preparations. All 4 patients had positive patch tests to eosin. The allergen is probably an impurity rather than eosin itself.

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.

Eosin-Nigrosin Staining Procedure
2016Eosin-Nigrosin is a staining technique that assesses the vitality of a sperm sample when the initial motility is less than 25 %. Nigrosin increases the contrast between the background and sperm heads, making sperm easier to visualize. Eosin stains only the dead sperm, turning them a dark pink, whereas live sperm appears white.
