Ag-staining of the nucleolus organizer region (NOR) was studied in the acrocentric chromosomes identified by Q-banding in repeated lymphocyte and skin fibroblast cultures from three different individuals. A similar pattern of Ag-stainability of NORs was found in the two tissues in each individual. S
A combination of the silver-staining method of the nucleolus organizer regions (NORs) with a Giemsa-banding method is described. This double staining allows a rapid identification of the NOR-bearing chromosomes.
The use of a combination of transmitted light and epiluminescence after silver and fluorescent staining of chromosome preparations makes it possible to achieve simultaneous visualization of silver-stained NORs and flourescent chromosomes. This technique permits exact localization of silver precipita
A reliable technique for staining human chromosomal nucleolar organizers (NOR's) with silver solutions is described. The NOR's can be selectively stained dark brown by silver solutions leaving the chromosome arms unstained and available for counterstaining with orcein or Giemsa dyes. Unequivocal ide
The inheritance of nucleolus organizer regions (NORs) was investigated by examining the degree of silver-staining in individual acrocentric chromosomes in two successive generations. The study was undertaken in six Down's syndrome children and their respective parents. Quinacrine fluorescent polymor
