Virus sampling tubes are used to collect, transport and store samples of influenza, avian influenza, coronavirus and other viruses for subsequent extraction and amplification. After collection of virus samples, it is often not possible to perform PCR testing in a timely manner at the sample collection site. Therefore, it is necessary to transport the collected virus swab samples.
The virus itself can rapidly dissolve into the body regrettably affecting subsequent testing. Therefore, a virus preservation solution needs to be added for storage and transport. For different testing purposes, different virus preservation solutions need to be used.
Currently, virus sampling tube manufacturers produce virus sampling tubes mainly divided into inactivated virus sampling tubes and non-inactivated virus sampling tubes. In order to meet different testing requirements and different laboratory conditions for virus testing, it is necessary to use different preservation solutions. So, what is the difference between inactivated and non-inactivated virus sampling tube preservation solutions?
The following virus sampling tube manufacturer provides a brief introduction in this article.
Inactivated virus sampling tube storage solution: Inactivated virus sampling tube storage solution can resolve and virus in the sample, and then the virus loses its infectious activity. It effectively prevents secondary infection by the operator, and it also contains inhibitors that prevent the degradation of viral nucleic acids before subsequent detection by NT-PCR. And it can be stored at room temperature for a relatively long time, thus saving the cost of virus sample storage and transportation.
Preservation solution for non-inactivated virus sampling tubes: The preservation solution for non-inactivated virus sampling tubes maintains the in vitro activity of the virus as well as the integrity of the antigen and nucleic acid, maintains the non-disintegrating viral protein envelope, and maintains the degree of viral sample originality. In addition to nucleic acid extraction and detection, it can be used for virus culture and isolation.
