2020 has entered the last quarter, and the research and development of the new crown vaccine is in full swing around the world, but before the large-scale vaccination of the vaccine, the nucleic acid detection of the virus is still a vital part of the anti-epidemic process. Therefore, Virus transport media and virus sampling tubes are still in huge demand. Which one is better, inactivated or activated?
According to different detection conditions and requirements, the Virus transport media is divided into two types: inactivated and activated. Among them, the inactivated type of Virus transport media contains high concentration of lysis salt, which can quickly lyse and inactivate the virus contained in the sample, but retain the viral nucleic acid; activated type will not inactivate the virus, but can be more completely retained The protein coat and nucleic acid of the virus. Therefore, both types of virus preservation solutions can be used for nucleic acid detection.
Virus transport media for nucleic acid detection
After the first round of national nucleic acid testing in China, it can be said that we have the world's leading level in terms of the efficiency and accuracy of viral nucleic acid testing. It also has mature technology and rich experience in the pre-processing of nucleic acid detection such as Virus transport media and virus sampling. So based on the experience of this period of time, is there a better choice among the two Virus transport media ?
As far as the current situation is concerned, it should be that two types of Virus transport media will co-exist, each of which has its own advantages. The inactivated virus preservation solution will inactivate the virus, so that it will not cause secondary infection, but this does not mean that the activated virus is likely to cause infection, because the mature technology, rich experience and strict control can completely eliminate The actual result of the secondary infection in the sampling process was that there was no virus transmission caused by the virus sampling tube.
Similarly, the virus retained by the activated Virus transport media is more complete and the detection is more accurate. It does not mean that the detection of the inactivated type is not accurate enough. In fact, through the improvement of detection technology and sophisticated instruments, the detection result is completely accurate and the detection is more accurate. The viable storage solution has lysed the virus protein, and the nucleic acid can be directly extracted for PCR experiment in the future.
Therefore, activated and inactivated Virus transport media should coexist for a long time. For manufacturers, only one type of preservation solution is more conducive to management and cost control than two types. Desheng still provides inactivated and activated versions. There are two types of active types, which are more convenient for the application enterprises to choose according to their requirements.
