It is produced by introducing positive or negative charges and hydroxyl groups into the benzene ring of tetrazolium salt. The WST of Polygold has sulfonic acid groups, and benzene rings are added directly or indirectly to improve water solubility. Dojindo also provides several newly developed phenylazo tetrazole salts, which can be easily reduced by NADH or other reducing agents to obtain orange or purple methylene dyes. Because of the use of phenylazo group, the color will change with heavy metal ions. Because the WST of DOGGETT has high water solubility, a solution of 10 mM- 100 mM with the same concentration can be prepared.
WST (water-soluble tetrazole) is a water-soluble tetrazole salt developed by Dawjindao, Japan. Compared with many previously developed tetrazole salts, WST is extremely low in water solubility and usually needs to be dissolved with detergent or organic solvent. WST is more suitable for cell activity detection, dehydrogenase detection, superoxide detection and reducing sugar detection. Such as WST-8 for cell counting kit -8(CCK-8), WST- 1 for SOD determination kit-WST; Medium. See table for the maximum wavelength of nail polish. The solubility of WST in water ranges from 10 mM to100 mm. Methylene dyes, especially type II dyes, have a wide spectrum and change with the progress of the reaction. Under alkaline conditions such as pH 1 1 to 12, the spectrum of methylene blue dye will also change greatly. Most water-soluble methylene dyes turn blue at high pH levels. Because tetrazolium salt is unstable in the presence of light, it needs to be stored away from light.
Wst is the abbreviation of Western Spoor Transmission Technology Co., Ltd..
Western Superconducting Materials Technology Co., Ltd. was established in Xi 'an Economic and Technological Development Zone in 2003, with a total area of 72 1 mu and a registered capital of 332.072 million yuan. The company is the main R&D and production base of special titanium alloy materials for aviation and biomedicine in China, and the only whole-process production enterprise of low-temperature superconducting alloy bars and wires in the world.
1WST water domestic waste classification system
WST wet domestic waste sorting system is a municipal waste treatment technology developed by Yang Zhiwei, chairman and president of Jiangsu Changjiang Machinery Group, and Xie Mingming, a Taiwanese businessman, after six years. It costs nearly 60 million. Now Yang Zhiwei has the exclusive manufacturing right and exclusive license right of this technology in China, and registered the copyright. In 2003, it passed the appraisal of scientific and technological achievements organized by Jiangsu Science and Technology Department. In 2006, it was rated as a national key new product by four ministries and commissions. In 2007, it was awarded the "High-tech Product Certification Certificate" by Jiangsu Science and Technology Department. It has also obtained invention patents from nearly 40 countries around the world and the priority of applying for world patents, and has a number of independent intellectual property rights.
