Application

Arsenazo III has been used as a color forming reagent to determine uranium concentration.

Biochem/physiol Actions

Arsenazo III is a metallochromic dye. Arsenazo III is used in the determination of calcium in biological samples. It is used to evaluate calcium transport in permeabilized cells. It is also used for the detection of rare earth metals (polyvalent metal ions). Arsenazo III is used for the spectrophotometric determination of uranium and thorium.

The Hoffmann method is a procedure for reference interval estimation using routine clinical results. Many authors incorrectly prepare Hoffmann plots on a linear rather than normal probability scale. We explore the consequences. This was investigated algebraically, by random number simulations

The widely used calcium dye reagent, o-cresolphthalein complexone, was replaced by the less well known metallochromic indicator Arsenazo III in a selective multitest analyser. Calibration stability increased from 12 hours to more than 48 hours. With the Arsenazo III reagent

The determination of proteins with arsenazo-DBN and Al3+ by Rayleigh light-scattering (RLS) is described. The weak RLS of arsenazo-DBN and BSA can be enhanced greatly by addition of Al3+ in the pH range 5.3-7.0; this resulted in two enhanced RLS
