Zinc Assay Kit Archives - Gen9 Genetics

Zinc is the second most abundant trace mineral in the body and is found in more than 300 metalloenzymes. Carbonic anhydrase, alkaline phosphatase, DNA and RNA polymerases could be listed as important examples. Due to its multiple biochemical functions, zinc deficiency is manifested by a variety of conditions. In cases of clinical deficiency, growth retardation and lightheadedness, impaired immune function, diarrhea, skin lesions, and alopecia are observed. Subclinical deficiency has effects on immune function, hormone synthesis and action, and neurological function.

The zinc found in the samples changes the red-orange color of 5-Br-PAPS to light pink under alkaline conditions. The change in absorbance at 548 nm is proportional to the level of total zinc in the sample. The assay can be calibrated with zinc sulfate dissolved in deionized water.
