Selenium Colorimetric Assay Kit

Selenium is an essential microelements in the human body. It participates in many metabolic pathways of the human body, and has the functions of delaying aging, enhancing immunity and preventing many diseases. The intake of the selenium through daily diet. Excessive intake of selenium can cause selenium poisoning, leading to multiple organ damage, and insufficient intake can also cause a variety of diseases, such as Kashin-beck disease, etc.
The detection principle of this kit: under acidic conditions, selenium is reduced to tetravalent selenium, and then reacts with the chromogenic agent to produce yellow complex, which increase the absorbance at 420 nm, and the color development intensity is proportional to the content of tetravalent selenium in the sample.
