Beschreibung

Allgemeine Beschreibung

Pyronin Y (C.I. 45005) is an aminoxanthene dye that is present as a weakly lipophilic cation in neutral aqueous solutions. It is also known as pyronine G.

Anwendung

Pyronin Y is commonly used in histology as a constituent of the ethyl (methyl) green-pyronine method for demonstrating DNA and RNA. It is known as a nucleic acid stain for both RNA and DNA. Additionally, it is suitable for other microscopic applications including demonstration of lipofuscin in neurons and simultaneous fixation and staining of phospholipids.

Eignung

Zertifiziert für den Einsatz in der Methyl-grün-Pyronin-Methode für differentielle Färbung von Nukleinsäuren.
