title: Mouse-human heterokaryon analysis with a 33258 Hoechst-Giemsa technique.
abstract: The bibenzimidazol derivative 33258 Hoechst can be used to distinguish microfluorometrically between mouse and human nuclei in heterokaryons.  This affords a quick and accurate alternative to autoradiography in the analysis of such heterokaryons.  The 33258 Hoechst fluorescence patterns can be converted after irradiation to a Giemsa rendition of the differential staining.
