|Product Overview :||Zinc Assay Kit is a quantitative colorimetric determination of zinc at 560 nm.|
|Storage :||Store the kit at +4°C and protect from light. Read the entire protocol before performing the assay. Synthetic rubber and glass can contain zinc which may leach into samples. For highest accuracy all glassware should be washed with dilute HCl, rinsed with distilled water and dried prior to use. Sample tubes such as Vacutainer and similar devices should be sealed with Parafilm rather than the butyl rubber stopper. Chelators such as EDTA will give artifactually low Zinc levels and should be avoided. Heparin, citrate and oxalate are acceptable anticoagulants. Most blood zinc (80%) is contained in erythrocytes and hemolysis will release large amounts into the serum. Abnormally high serum values obtained suggest the collection of another sample and retesting.|
