Biological Electron Microscopy: Theory, Techniques, and ...
Uranyl stains are usually used at pH 3.5-4 and strongly stain proteins. If the pH is
adjusted to higher levels, DNA becomes more strongly stained. One of the most
important features of uranyl stains is that they serve as mordants for lead stains.

Electron Microscopy: Principles and Techniques for Biologists
Adjustment of the uranyl stain to a pH of 5.2 also leads to the fine structural
preservation of DNA as well as cell junctions, mitochondria, myofibrils,
nucleoproteins, and phospholipids. Depending on the specimen, ultrastructural
preservation is ...

Metal Ions in Biology and Medicine
For a 300 uM uranium concentration, uranyl-bicarbonate stock solution led to W7
( dead cells, whereas a uranyl-citrate solution led to 82% cell death. For a 600
uM uranium concentration, both uranyl-bicarbonate and -citrate led to total cell ...

Stains and Cytochemical Methods
Also, the presence of uranyl in lipoproteins increases their dye-binding capacity (
Lozsa. 1974). Comparative studies indicate that uranyl acetate is superior to
uranyl nitrate in terms of membrane stabilization and staining. Some uranyl ions ...

Liquid Membranes: Chemical Applications
Carrier-mediated transport of uranyl ion. Uphill transport of uranyl ion has been
extensively investigated due to its great practical importance. It was typically
achieved with cellulose triacetate membrane containing tributyl phosphate as a ...

Electron Microscopy: Methods and Protocols
This process commonly consists of staining in aqueous solutions of uranyl
acetate followed by lead citrate and can result in good consistent quality staining
if certain precautions are taken. This chapter covers conventional and alternative
