title: Feulgen type staining of mammalian tissues with Dahlia-SO2.
abstract: The use of the basic dye, Dahlia, which belongs to triphenylmethane group but without a primary amino group in its molecule has been described as useful in the staining of aldehyde groups of acid hydrolysed DNA in tissue sections following the conventional Feulgen procedure. Dahlia-SO2 prepared with sodium hydrosulphite is highly suitable when used at pH 4-0 to 5-0. The absorption characteristics of the stained nuclei indicate on the peak of maximum absorption at 560 nm, whereas, that of the aqueous dye solution is at 590 nm.
