General description

Chloride is an essential anion needed for the proper functioning of many critical aspects of metabolism, including aiding in maintenance of the body′s acid-base balance. In Cystic Fibrosis, mutations to the CF transmembrane conductance regulator (CFTCR) gene result in altered sodium and chloride ion transport channels.[1]

Application

Chloride Assay Kit has been used to measure chloride concentration spectrophotometrically and is used to measure chloride levels in blood plasma of toads Rhinella marina.[2][3][1]

Suitability

Suitable for the quantification of Chloride in a variety of biological samples. Blood and urine can be used directly after dilution with water

Principle

The Chloride Assay kit provides a simple and direct procedure for measuring chloride in a variety of samples, including blood and urine. Chloride concentration is determined by a competition reaction between Hg2+ and Fe2+ for 2,4,6-Tris(2-pyridyl)-s-triazine(TPTZ). The preferred Hg-TPTZ complex exhibits no color. In the presence of chloride, Hg2+ forms HgCl2, which precipitates, allowing TPTZ to complex with Fe2+. The Fe-TPTZ complex results in a colorimetric (620 nm) product proportional to the chloride present.

Questions

  1. What is the detection range of this assay?

    1 answer

    1. The assay is linear in the 20 - 120 nmol Chloride/well range, with a detection sensitivity of approximately 0.4 mM Chloride. There is slight nonlinearity below 20 nmol of Chloride. Samples falling below 20 nmol should be repeated with 3 to 5-fold higher samples.
