Feulgen stain
(Science: technique) a selective cytochemical reaction for dna in which sections or cells are first hydrolyzed with hydrochloric acid to produce apurinic acid and then are stained with schiffs reagent to produce magenta-stained nuclei; generally the concentration of dna in nucleoli and mitochondria is too low to permit detection by this stain
