Test Name: Feulgen
Methodology: Special Stains
Feulgen stain is a staining technique discovered by Robert Feulgen and used in histology to identify chromosomal material or DNA in cell specimens. Schiff’s aldehyde reagent is the stain used. The great value of the Feulgen procedure is the manner in which cells are pretreated so that DNA furnishes the only available aldehyde to react with Schiff’s reagent.
