| Message: | Glycerin, also known as glycerol, is a colorless, sweet, clear and viscous liquid, odorless, and has a warm and sweet taste. It can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon disulfide, petroleum ether and oils. Glycerol is the backbone component of triglyceride molecules. When the human body consumes edible fat, the triglycerides in it are metabolized and decomposed in the body to form glycerol and be stored in fat cells. Therefore, the end products of triglyceride metabolism are glycerol and fatty acids.
At present, the main components of the virus preservation solution are Hank's solution base, gentamicin, fungal antibiotics, BSA (bovine serum albumin fifth component), biological buffer TRIS, amino acids, cryoprotectants, glycerin and other components. Among them, glycerin has the function of nutrient and desiccant. The virus does not have strong resistance to the outside world and is sensitive to temperature. The 50% concentration of glycerol keeps the preserved material in a relatively static state.
Desheng began to develop the virus preservation solution at the beginning of the epidemic. After the company's R&D staff worked overtime and many trials and discussions, the development was finally successful, and the products were well received after customers used them. Now there are dozens of stable customers. The temperature is declining and winter is approaching. Experts predict that the new coronavirus may strike again. In order to strictly prevent the new coronavirus, a virus preservation solution for nucleic acid testing is essential. |
