Merck, MAK496-1KT, Zinc Assay Kit

General description
Zinc is an essential trace element and plays many key roles in metabolism. It is required for the activity of more than 300 enzymes, the structure of many proteins, and control of genetic expression. Zinc status affects basic processes of cell division, growth, differentiation, development, performance and aging through its requirement for synthesis and repair of DNA, RNA and proteins. The common causes of zinc deficiency are low dietary intakes and low bioavailability. Clinical signs of zinc deficiency include acrodermatitis, low immunity, diarrhea, poor healing, stunting, hypogonadism, fetal growth failure, teratology and abortion. Zinc deficiency has now been recognized to be associated with many diseases such as malabsorption syndrome, chronic liver disease, chronic renal disease, sickle cell disease, diabetes, malignancy, and other chronic illnesses.
Application
The kit is suitable for the determination of zinc in serum, plasma, urine, saliva, waste water, soil, etc, as well as for studying the effects of drugs on zinc metabolism.
Biochem/physiol Actions
The Zinc Assay Kit is designed to measure zinc directly in biological samples without any pretreatment. The method utilizes a chromogen that forms a colored complex specifically with zinc. The intensity of the color, measured at 425 nm, is directly proportional to the zinc concentration in the sample.
Features and Benefits

• Linear detection range 0.12 µM (0.78 µg/dL) to 10 µM (65 µg/dL) zinc
• Compatible with high-throughput handling systems.
• The optimized formulation has greatly enhanced reagent and signal stability.
