The cation UO₂²⁺, present in some compounds of uranium.
‘uranyl acetate’
‘As the amine sulfate reacts with the uranyl ions, the uranium is converted from a water-soluble compound into one that is kerosene-soluble.’
‘Then, we fix the adsorbed DNA molecules in their conformations thanks to uranyl acetate and we dry the sample using filter paper.’
‘The drying step is performed after using a 0.02% diluted uranyl acetate solution for fixing the DNA molecules in their conformations.’
‘After incubation, the sections were washed thoroughly with distilled water and counter-stained with uranyl acetate and lead citrate as described above.’
‘Staining with lead citrate and uranyl acetate is required as organic material is very electron translucent, and thus contrast is poor without a heavy metal stain.’
‘Sections were collected in water on copper grids, stained with uranyl acetate and lead citrate, and viewed on a Philips transmission electron microscope.’
‘The specimens were then stained with uranyl acetate and lead citrate for 15 minutes, respectively.’
‘For electron microscopy, thin sections of the same material were stained with uranyl acetate and lead citrate.’
‘Thin sections of the tumor were stained with uranyl acetate and lead citrate.’
‘Sections were picked up on 200 mesh copper grids and further stained with uranyl acetate and lead citrate.’
