Beschreibung

Allgemeine Beschreibung

Eosin has been used in combination with methylene blue, to detect carboxlic acid group in organic compounds. It gives a red or orange-coloured precipitate on treatment with carboxylic acid solution in water, acetone, alcohol, or dioxin. It is also used as an indicator for differentiation of the colon from the typhoid-dysentery group of bacteria.

Mischung von Eosin- und Methylenblau-Farbstoffen für Differentialmedien für die Kultur und Identifizierung pathogener Mikroorganismen, z.B. Neisseria sicca,, Acinetobacter calcoaceticus.

Anwendung

Eosin methylene blue was used for staining cells, during optical microscopy studies, done for analysis of cell morphology.
