Desheng is a new scientific and technological enterprise specializing in the research and development, production and sales of blood collection additives, chemiluminescence reagents, biological buffers and in vitro diagnostic reagents. Acridine ester series of products are the company's research and development of ultra-high sensitivity chemiluminescence substrate reagents. Under alkaline conditions, the acridine ester molecules can be attacked by hydrogen peroxide to form dioxane, which is unstable and decomposes into CO2 and n-methylacridone in the electron excited state. When it returns to the ground state, it emits light with wavelength of 430 nm. It does not need catalyst, and the luminescence system is simple. Desheng has seven acridine ester products with different groups: 1. Ae-nhs (traditional acridine ester); 2. Dmae-nhs; 3. Me-dmae-nhs; 4. Nsp-dmae-nhs; 5. Nsp-sa-nhs; 6. Nsp-sa; 7. Nsp-sa-adh. These acridine esters produced by Desheng have the characteristics of high purity and small difference between batches. Besides, it provides other immune reagents for matching use and provides a complete set of technical services and technical support.
