Photoinduced off-switching of organic fluorophores is used in super-resolution microscopy to separate and localize single fluorescent molecules. However, this method typically relies on the use complex imaging buffers that make enzymatic oxygen scavengers remove primary thiols reversibly reduce excited a non-fluorescent state. Here, we show interactions between sodium sulfite glycerol can also ...

A new pigment, desulforubidin, that has sulfite reducing activity, has been purified from extracts of the Norway strain of Desulfovibrio desulfuricans, which lacks desulfoviridin.

Deprotection of phosphate, phosphate, and sulfite esters by silica chloride is described. Silica chloride is a mild, selective, and effective reagent for cleavage of benzyl and t-butyl esters of the above compounds.

The activity of sulfite oxidase increased in intact rat hepatic mltochondria and decreased in solubilized mitochondria during poisoning by cc1 iI' During acute damage the sulfite oxidase activity of the post-mitocho drial supernate increased, while the total activity in the hepatocyte declined. Thus, the outer membrane loses its selective permeability to macromolecules coincident with the decli...
