Abstract: | Cytofluorometry and cytophotometry (Feulgen staining) as well as ultraviolet cytophotometry revealed similar histograms of DNA content in squashed nuclei of rat cerebellar Purkinje cells. More than 90% diploid (2c) cells and 1% tetraploid (4c) cells were obtained. DNA content in other Purkinje cells ranged between the 2c and 4c level. |
