Uranium acetate

Foiin s mixture (for uric acid) dissolve 500 g of ammonium sulfate, 5 g of uranium acetate, and 6 mL of glacial acetic acid, in 650 mL of water. The volume is about a liter.

To avoid loss of gold-labeled Ab during staining with the acidic uranium acetate, fix the sections with glutaraldehyde for 15 min. 

Then rinse them with distilled water, and stain with uranium acetate for 30 min at 37°C for Lowicryl and 15 min at room temperature for LR White and LR Gold. They may then be stained further with a conventional lead stain (see Note 4). 

For sufficient contrast, most specimens will require lead staining after the uranium acetate stain. Although all conventional lead stains can be used, we found staining with Millonig s lead hydroxide for 2 min under N2 best for Lowicryl and LR Gold embedded material. 

In testing for cochineal, the liqueur is diluted with water and acidified with acetic acid, the liquid obtained being then shaken with amyl alcohol. The alcoholic layer is separated and evaporated with addition of a little water, the residue being treated with a few drops of 3% uranium acetate solution. In presence of cochineal, a bluish-green coloration or precipitate is produced, this changing to orange on addition of an add. 

In the belief that the action of the enzyme might be modified by the presence of some of the more prevalent metals in trace amounts, the effects of cations on mammalian /3-glucuronidase were re-investigated186 195 of a large number studied, only Cu , Ag , and Hg were pronounced in their effects. (Inhibition was also seen with uranium acetate, ammonium chloroplatinate, osmium tetroxide, and sodium tungstate.83) Marked inhibition was seen with 2.5 X 10-6 M of Ag and 1.5 X 10 6 M of Hg00, and inhibition by these two ions was reversed by tissue constituents.
