The correlation between silver-staining and DAPI-induced chromosome undercondensation
The silver-staining pattern of Chinese hamster chromosomes that show DAPI-induced undercondensed areas was studied. The Ag-staining
was preceded or not by dehistonizing treatments. In both cases silver preferentially precipitates on undercondensed areas.
It is suggested that this phenomenon could be compared to the silver-stainability of the active NORs during mitosis when they
remain undercondensed. The possible chemical nature of the protein groups responsible for the silver-staining is discussed.
