sod(超氧化物歧化酶)多少钱（SOD (superoxide dismutase) how much is it） SOD (superoxide dismutase) how much is it? SOD is a natural scavenger of oxygen free radicals in organisms. It has extensive medical value and can be used as additives in medicine, food and daily chemical products. SOD has been approved for clinical use, showing strong regenerative repair for tissue sclerosis and fibrosis caused by age, disease, or injury. SOD has been successfully applied to adjuvant therapy after radiation therapy, to control the progression of heart disease and to treat severe rheumatoid arthritis. In Denmark, rheumatoid arthritis is treated by injecting SOD. SOD is an abbreviation of superoxide dismutase (superoxidedismutase). It is an active protease containing metal elements. It is a world-class, high, sharp and delicate subject in biology, medicine and life science. Most of the worldwide development of superoxide dismutase (SOD), which is extracted from animal blood, is expensive. Our country has 60000 yuan /g-70000 yuan /g The catalytic substrate for superoxide dismutase (SOD) is O2, which generally takes the amount of product production or substrate consumption as the unit of enzyme activity in a given time. Since O2 is very unstable and difficult to prepare, the method of measuring SOD is usually indirect except for a few direct methods. 1. the principle of direct method is to determine the amount of disproportionation of O2 according to the properties of O2 or the substance that produces O2, thus determining the activity of SOD. The classical direct methods include pulse radiolysis, electron paramagnetic resonance (EPR), and nuclear magnetic resonance (NMR). Due to the expensive equipment required, it is generally less used. 2., the common feature of these methods is to have a O2 producing system and a detectable system which can be reduced or oxidized by O2. In the presence of SOD, a part of O2 is disproportionation by SOD, so the reaction of O2 reduction or oxidation detection s
