The magnetic susceptibility of ferricyanides
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19721. The magnetic susceptibility of ferricyano complexes with uni-, di-, and trivalent cations, as well as polycyanides, containing another of the elements of the first transition series in addition to iron, was measured in the temperature interval 80–300°K. 2. The influence of cations in ferri complexes on the magnetic properties of iron (

Photophosphorylation accompanying the hill reaction with ferricyanide
Biochimica et Biophysica Acta, 1962A study of the dependence upon pH of ferricyanide photoreduction revealed that the reaction was most rapid but least stable at high pH (above pH 8) and that inadequate buffering could readily lead to differences in rate due to pH changes. Since the occurrence of phosphorylation may be associated with a pH change, precautions are necessary to prevent ...

The use of potassium ferricyanide in neural fixation
The Anatomical Record, 1980AbstractThe present study suggests a mixture of buffered osmic acid and 1.5% potassium ferricyanide as a post‐fixation to improve the fixation of neural tissue. This procedure results in an improved preservation of membranes as well as cytoplasm and cytoplasmic organelles.

Transmembrane ferricyanide reduction in carrot cells
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1985Carrot cells (Daucus carota) grown in tissue culture are capable of reducing the non-permeable electron acceptor, ferricyanide, with concomitant proton extrusion from the cell. Optimum conditions for transmembrane ferricyanide reduction include a pH of 7.0-7.5 in a medium containing 10 mM each KCl, NaCl and CaCl2.

Determination of mercapto groups in ovalbumin with ferricyanide
Archives of Biochemistry and Biophysics, 1959Abstract A precise determination of the mercapto-group content of denatured ovalbumin has been made with potassium ferricyanide in phosphate buffer at pH 7.1 by means of a novel amperometric method. The results indicate 4.0 groups per molecule of 45,000 molecular weight. This has been confirmed by spectrophotometric measurements.

Effect of hemoglobin on ferricyanide-dependent assays
Analytical Biochemistry, 1970Abstract Aged solutions of ferricyanide have been shown to interfere with the spectrophotometric assay of enzyme preparations containing hemoglobin by virtue of the presence of cyanide ion. The use of 412 mμ is recommended.

Vitamin E Oxidation with Alkaline Ferricyanide
Science, 1963Oxidation of dl -α- tocopherol or its model, 6-hydroxy-2,2,5,7,8-pentamethylchroman, with alkaline ferricyanide yields a variety of products. In addition to the known dimeric keto ether, two new products, compound A, a trimer, and compound B, an isomer of compound A, were ioslated.

Ferricyanide Reduction Method for Reducing Sugars
Nature, 1960THE ferricyanide reduction method and its modifications1–3 for the determination of reducing sugars are among the more commonly used techniques for this purpose. They depend on the spectrophotometric measurement of the amount of prussian blue formed when excess ferric iron is added to the reactant mixture.
