British journal of haematology, 75(4), 615-616 (1990-08-01)
Certain modifications to the previously published ICSH recommendations (1978) have been approved by the Iron Panel of the International Committee for Standardization in Haematology (ICSH). They include substitution of the chromogen bathophenanthroline sulphonate with ferrozine or ferene, which are more

(4-hydroxyphenyl)pyruvate dioxygenase (HPPD) catalyzes the second step in the pathway for the catabolism of tyrosine, the conversion of (4-hydroxyphenyl)pyruvate (HPP) to homogentisate (HG). This reaction involves decarboxylation, substituent migration, and aromatic oxygenation. HPPD is a member of the alpha-keto acid

Ferene-S was tested as the iron chromogen and the results were compared with the chromogen Ferrozine. With Ferene-S the volume of serum could be halved. We also tried to adapt Ferene-S in total iron binding capacity determinations but failed. From

We describe a modification of a previously described serum iron procedure applied to the Bayer DAX48 (Bayer Diagnostics, Tarrytown, NY) automated chemistry analyzer. The iron-ligand used in this assay, 2-(5-nitro-2-pyridylazo)-5-(N-propyl-N-sulfopropylamine) phenol (nitro-PAPS), has a molar absorptivity of 94,000 L mol(-1)

Superoxide and hydrogen peroxide are often ascribed iron reducing roles in reactions leading to the formation of an aggressive oxidant by Fenton Chemistry. Hydrogen peroxide, however, does not appear to reduce iron in Fenton reactions, and we here show that

Nonheme iron proteins can be visualized as blue bands in native polyacrylamide gels using a staining method that is both simple and rapid. The reaction of potassium ferricyanide with protein-bound iron atoms to form royal blue complexes occurs almost instantaneously

Ferricyanide reduction frequently is analyzed to determine the activity of membraneous reductases. An improved, highly sensitive, and rapid method for quantitative endpoint determination of ferrocyanide is presented. Ferrocyanide is oxidized by Fe(3+) in the presence of Ferene-S under acid conditions

A comparison of three sensitive ligands for iron is described. All show varying degrees of enhancement of values by copper, an element that is the primary interference encountered in serum assays for iron. Two of three tested reagents, 2,4-bis(5,6-diphenyl-1,2,4-triazin-3-yl) pyridine

S-nitrosylation, the oxidative modification of Cys residues by nitric oxide (NO) to form S-nitrosothiols (SNOs), modifies all main classes of proteins and provides a fundamental redox-based cellular signaling mechanism. However, in contrast to other post-translational protein modifications, S-nitrosylation is generally

A new method for specifically staining the iron atoms present in transferrin and lactoferrin after polyacrylamide gel electrophoresis and isoelectric focusing is described. The stain, 3-(2-pyridyl)-5,6-bis(2-(5-furylsulfonic acid))-1,2,4-triazine, disodium salt, or Ferene S, will detect transferrin in 5 microliters of human
