In situ separation of nucleolar components by hypotonic treatment of cells.

Author information

Institute of Experimental Medicine, Czechoslovak Academy of Sciences, Prague.


The main features of the reaction of nucleolar components to a simple hypotonic shock are described. In place of nucleoli, only fibrillar complexes remain. Such preservation provides another morphological proof of the hypothesis of fibrillar complexes as morphological-functional units in active nucleoli. Moreover, this method can become a good tool for further study of nucleolus-organizing regions.
