We report here on a new sensitive and highly specific DNA staining technique which we have called sulpho-DNA staining. DNA staining is based on a sulphonylation reaction of 2'-deoxycytidine or cytidine that takes place in the 6th position of cytosine with ensuing immunodetection of the sulphonylated DNA. The specificity of DNA staining is introduced by the use of an antibody recognizing only modified DNA but not modified RNA, by recourse to an additional acid hydrolysis step which destroys RNA but not DNA. We describe here the optimal conditions for the sulphonylation of DNA using O-methylhydroxylamine and metabisulphite as reactants. The new DNA stain labels all nuclei in either normal human tissue or in tumor cells. For nuclear DNA the staining signal is higher for the sulpho-DNA staining than for the Feulgen staining for nuclear DNA. This new DNA staining technique is suitable for use on tissue sections as well as on cytosmears.
