Application

Pyronin Y has been used:
  • in the purification of quiescent and cycling hematopoietic stem cells and staining of bone marrow cells (HSCs)
  • as a component of the polychlorinated biphenyls (PCBS) solution for staining mammary gland side population cells (MG-SPs)
  • staining of CD34+ cells

Biochem/physiol Actions

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.

Preparation Note

This product is soluble in water 1 mg/ml, yielding a clear dark red solution.
