Abstract/OtherAbstract:
The AT specificity of the fluorochromes DIPI and DAPI and the GC specificity of mithramycin are evidenced by observations in human, mouse, and bovine chromosomes. DIPI and DAPI produce a pattern similar to Hoechst 33258 in all three species, whereas mithramycin results in a reverse pattern. The AT-rich centromeric heterochromatin in mouse is brilliantly stained by DIPI or DAPI and remains nearly invisible after mithramycin staining. In the GC-rich centromeric heterochromatin of cattle the opposite behavior is observed.
