Uranyl acetate is the acetate salt of uranium oxide, a toxic yellow-green powder useful in certain laboratory tests. Structurally, it is a coordination polymer with formula UO 2 (CH 3 CO 2) 2 (H 2 O)·H 2 O.

2009年5月28日 · Uranyl acetate appears as yellow crystals with a slight odor of vinegar. Density 2.89 g / cm3. Uranyl acetate is a chemical compound of uranium. It is used as a negative stain in electron microscopy. Uranium is a chemical element that has the symbol U …

Uranyl acetate is the uranium salt normally used in TEM, although uranyl nitrate and magnesium uranyl acetate are also effective. The uranyl ions combine in large quantities with phosphate groups in nucleic acids, as well as phosphate and carboxyl groups …

Uranyl Acetate and Uranyl Nitrate are water-soluble Uranium compounds used for staining slides in electron microscopy. Laboratories can purchase Uranium and other staining compounds for the preparation of samples under a Nuclear Regulatory Commission (NRC)

Moreover, uranyl acetate can inhibit other non-zinc finger DNA-binding proteins to a similar extent, suggesting a disruption of protein-DNA interaction by nonspecific protein interactions. Therefore, these observations indicate a potential mechanism for the cytotoxic and mutagenic carcinogenic effects of uranyl ions [ 84 ].

Uranyl acetate (UAc) is a yellow compound that contains a small amount of radioactive uranium. There are three isotopes of uranium that occur in nature, and each is radioactive. U-238 makes up the bulk of naturally occurring uranium, at 99.27%, with U-235 and U-234 making up 0.72% and 0.006% respectively.

Uranyl acetate is a substance used in neuroscience research methods to enhance the retention of membrane cholesterol in cryosections, aiding in the preservation of cellular structures for electron microscopy analysis.

Standard uranyl acetate stain is alkaline, thus overstaining causes deprotonation of cationic polymers with low pK a, leading to decondensation of their complexes. Staining by neutralized uranyl acetate, which has ionic strength of about 1 M, can also likewise decondense complexes.

Uranyl acetate and uranyl nitrate are water-soluble uranium compounds and are often used as stains in electron microscopy. Even with the relatively small amounts used in microscopy, there are associated chemical and radiological hazards which require some basic safety precautions to be adopted; with the emphasis on avoiding the possibility of ...

2017年2月28日 · This monograph for Uranyl Acetate Dihydrate provides, in addition to common physical constants, a general description including typical appearance, applications, change in state (approximate), and aqueous solubility.
