Pyronin Y

Description

Marker dye for RNA useful in acid buffer systems | CAS: 92-32-0 | C17H19ClN2O | 302.802 g/mol

Pyronin Y is a cationic dye that intercalates RNA and is visible as a red band during electrophoresis. It has also been shown to accumulate in mitochondria of viable cells. In conjuction with Methyl Green or Nancy-520, Pyronin Y can be used as a fluorescent differential stain of nucleic acids in paraffin tissue sections.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
