Sentences

- The enzyme is reoxidized with an excess of a mediator reagent, such as a ferricyanide ion, a ferrocene derivative or osmium bipyridyl complex.
- Iridite 14-2, a chromate conversion coating for aluminum, contains chromium ( IV ) oxide, barium nitrate, sodium silicofluoride and ferricyanide.
- Potassium ferricyanide reacts with ferrous iron in acidic solution to produce the insoluble blue pigment, commonly referred to as Turnbull's blue or Prussian blue.
- The print is washed to remove excess potassium ferricyanide, and then immersed into a bath of toner, which converts the silver halides to silver sulfide.
- The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide ( Turnbell's blue identical to Prussian blue ) with the divalent iron.
- Potassium ferricyanide is often used in physiology experiments as a means of increasing a solution's redox potential ( E?~ 436 mV at pH 7 ).
- Compared to normal cyanides like potassium cyanide, ferricyanides are much less toxic because of the tight hold of the CN & minus; to the Fe 3 +.
- Having established the composition of Prussian blue, Gadolin suggested a method for precipitating ferrous iron as ferro ferricyanide, preceding the work of Gay-Lussac by forty years.
- Ferricyanide is able, in vivo and in vitro, to promote inactivation of FNR function or [ 4Fe 4S ] . FNR destruction by means of oxidizing the cluster.
- Potassium ferricyanide is used in many amperometric biosensors as an electron transfer agent replacing an enzyme's natural electron transfer agent such as oxygen as with the enzyme glucose oxidase.
- In a typical procedure, equal volumes of an 8.1 % ( w / v ) solution of potassium ferricyanide and a 20 % solution of ferric ammonium citrate are mixed.
- In the case of silver stained protein bands the destaining is accomplished by oxidation of the metallic silver attached to the protein by potassium ferricyanide or hydrogen peroxide ( H 2 O 2 ).
- These observations are explained in terms of a proposed method in which phosphate esterfies during electron transport reactions, leading to the reduction of ferricyanide, and the rate of electron transport is limited by the rate of phosphorylation.
- It is common practice to perform this reaction using a catalytic amount of osmium tetroxide, which after reaction is regenerated with either potassium ferricyanide or " N "-methylmorpholine " N "-oxide.
- The dilution technique will not cause a further increase in the rate in which ferricyanide is reduced with the accumulation of light intensities, it is concluded that the effect is largely on the light-independent steps of the Hill reaction.
- The association of phosphorylation and the reduction of an electron acceptor such as ferricyanide increase similarly with the addition of phosphate, magnesium ( Mg ), and ADP . The existence of these three components is important for maximal reductive and phosphorylative activity.
- Potassium ferricyanide is also one of two compounds present in ferroxyl indicator solution ( along with phenolphthalein ) which turns blue ( Prussian blue ) in the presence of Fe 2 + ions, and which can therefore be used to detect metal oxidation that will lead to rust.
- Further experiments to prove that the oxygen developed during the photosynthesis of green plants came from water, were performed by Hill in 1937 and 1939 . He showed that isolated chloroplasts give off oxygen in the presence of unnatural reducing agents like iron oxalate, ferricyanide or benzoquinone after exposure to light.
- Potassium ferrocyanide is used in a mixture with potassium ferricyanide and phosphate buffered solution to provide a buffer for beta-galactosidase, which is used to cleave X-Gal, giving a bright blue visualization where an antibody ( or other molecule ), conjugated to Beta-gal, has bonded to its target . On reacting with Fe ( 3 ) it gives a Prussian blue colour.
