Chinese scientists successfully developed sibutramine test strips
Chinese scientists successfully developed sibutramine test strips November 19, 2018 Source: Ministry of Science and Technology Sibutramine is a central nervous system suppressor that was approved by the US FDA for obesity treatment in 1997 and became a weight loss star. With the promotion and use of sibutramine, the researchers found that sibutramine can increase the risk of cardiovascular and cerebrovascular diseases, leading to endocrine and metabolic disorders, mental stress, and sleep disorders. Since 2010, the United States, the European Union, and China have successively blacklisted sibutramine and strictly prohibit the addition of sibutramine to health foods, cosmetics, and pharmaceuticals. However, sibutramine has not disappeared, and rapid screening of sibutramine is particularly important. Under the support of the national key research and development plan “Key research and development of key technologies for food safetyâ€, Chinese scientists have labeled sibutramine-specific antibodies for colloidal gold according to the principle of immunocompetitive analysis, and solid-phased them in glass fibers. Then, sibutramine complete antigen and goat anti-mouse secondary antibody were sprayed on the nitrocellulose membrane as a detection line (T line) and a quality control line (C line), and the free sibutramine in the sample to be tested The solid phase antigen on the nitrocellulose membrane competes with the colloidal gold-labeled antibody. The higher the concentration of sibutramine in the sample, the lighter the T-line coloration. When the sibutramine content is higher than 200 μg/kg, the T-line is completely absent. Color development. The test strip is easy to operate, and the detection time is only 5 minutes. With the colloidal gold quantitative analyzer, the detection sensitivity can reach 40μg/kg. The test results are reproducible and accurate. The core technology has won 2 Chinese invention patents. Test strips have been procured by the Thai Food and Drug Administration for screening for abuse of sibutramine in market slimming products. Aging is a natural process, and oxygen free radicals are the number one killer of accelerated aging of the skin and body.
