Related introduction:

This product is a bioengineered Cu-Zn superoxide dismutase produced by fermentation and purification of engineering bacteria containing human Cu-Zn superoxide dismutase gene using yeast powder, peptone, glucose and other raw materials. Superoxide dismutase (SOD) is a kind of active protease containing metal trace elements, widely distributed in various organisms, such as animals, plants, microorganisms, etc. Its main members are Cu, Zn-SOD, Mn-SOD and Fe-SOD. SOD has special physiological activity, which can convert harmful superoxide anion free radicals into hydrogen peroxide. It is the primary substance for scavenging oxygen free radicals in organisms. The SOD of Neon has high activity verified by SGS, and has great advantages in the industry. It has been confirmed that there are more than 60 kinds of diseases caused by oxygen free radicals, and the level of SOD in organisms has become an intuitive indicator of aging and death of organisms. SOD can resist and block the damage caused by superoxide free radicals to cells, and repair the damaged cells in time. It plays an increasingly important role in the biological antioxidant mechanism. It is one of the substances approved by the Ministry of Health of China with the functions of anti-aging, immune regulation, blood lipid regulation, anti-radiation and beauty.

Matters needing attention:

1) If it cannot be used at one time, please prepare the mother solution before use and sub-pack it into small specifications and store it at – 20 ℃ to avoid repeated freezing and thawing affecting the protein activity;

2) Avoid the use of strong acids, strong alkalis, strong oxidants, high concentration organic solvents and other reagents that are easy to cause protein denaturation;

3) This product is only used for scientific research.
