When it comes to virus preservation solution, you must be familiar with it. As its name is, it is the liquid used to preserve the virus. When we are making COVID-19 nucleic acid, after taking the throat swab, the medical staff will break off one end of the sample and put it into a test tube containing red liquid for preservation, and then send it to test. The red liquid here is the virus preservation solution.

The virus preservation solution plays a role as a transport medium in the process of sending nucleic acid detection samples to avoid the destruction of viral nucleic acid, resulting in undetectable or false negative phenomena. Since the outbreak of the epidemic in 2019, the high frequency of all nucleic acid testing and guaranteed sample preservation media have played an immeasurable role in timely detection results and effective control of the spread of the epidemic. There are two kinds of virus preservation solutions: inactivated and non inactivated.

The main appearance of inactivated virus preservation solution is colorless because its components are colorless. It has the effect of inactivating the virus. By adding bio buffer, lysate, EDTA, etc., the virus can be instantly lysed to release nucleic acid, which can be detected by subsequent real-time fluorescence to determine whether it is infected with the virus.

The non inactivated virus preservation solution is different. At present, the mainstream appearance in the market is red, because the pH indicator is added. It is bright red in neutral, yellow in acidic, and purple red in alkaline. The detection personnel can quickly judge whether the pH value of the virus preservation solution has changed and deteriorated through the change of color. It can prolong the survival time of the cells parasitic on the virus in vitro, indirectly add liquid components to improve the survival rate of the virus, maintain the integrity of the virus, improve the accuracy of nucleic acid detection, and can also carry out research beyond the retention of viral nucleic acids.

Desheng Biochemical has been engaged in the research, development, production and sales of raw materials for in vitro diagnostic testing reagents for more than ten years. The inactivated virus preservation solution and non inactivated virus preservation solution produced by Desheng Biochemical conform to the social form and are favored by major COVID-19 testing manufacturers. You are welcome to consult and order from the government.
