[′yu̇r·ə‚nil ′as·ə‚tāt]
(inorganic chemistry)
UO2(C2H3O2)2·2H2O Poisonous, radioactive yellow crystals, decomposed by light; soluble in cold water, decomposes in hot water; loses water of crystallization at 110°C, decomposes at 275°C; used in medicine and as an analytical reagent and bacterial oxidant. Also known as uranium acetate.

Freshly glow-discharged, Formvar-coated, 400-mesh copper grids (SPI Supplies) were incubated for 10 min on the SV drops, washed three times for 10 min each in squid 1/2X buffer, and stained with 1% uranyl acetate in water.
The fixed ovaries were contrasted in 2% uranyl acetate in 10% alcohol during 6 hours and then dehydrated in a standard acetone series (70, 90, and 95%, five minutes each and then three changes of 100% 5 minutes each) and embedded in Epon-Araldite.
Since living specimens must be dehydrated, frozen, or fixated using a negative staining material such as uranyl acetate or plastic embedding, this makes it difficult to see the ever-changing movements that characterize a living cell.
