Enzyme-labeled secondary antibodies are a class of specific, sensitive and safe immunochemical agents widely used in various branches of immunology, molecular biology and clinical medicine. At present, it is more common to use horseradish peroxidase (HRP), which is oxidized by sodium iodate and labeled on an antibody IgG molecule to prepare an HRP-antibody conjugate. All kinds of enzyme standards provided by our company are marked according to the modified sodium periodate oxidation method established by our laboratory. A certain concentration of BSA has been added to each finished product as a stabilizer. The working concentration of the product is different according to the method. It is best to freeze at -20 °C before use to avoid repeated freezing. Usually used in immunohistochemistry, western blot (western blot).

Natural sweeteners refer to food additives that can sweeten soft drinks. They can be divided into natural sweeteners and synthetic sweeteners according to their sources.
Natural sweeteners are substitutes for sugar. Natural sweeteners considered to be generally safe include stevia, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium. Natural sweeteners have many uses in the home and in processed foods.
Natural non-nutritive sweeteners are increasingly paid attention to, is the development trend of sweeteners, WHO pointed out that diabetes patients have reached more than 50 million, more than a quarter of the American people require low-calorie food. In sucrose substitutes, the United States mainly uses aspartame, up to more than 90%, Japan mainly uses stevia glycoside, and Europeans are more interested in AK sugar (acesulfames). All three non-nutritive sweeteners are available in China.
