Virus sampling tubes are used to collect, transport and store influenza, avian influenza, coronavirus and other viral samples for subsequent extraction and amplification. After virus samples are collected, it is usually not possible to perform PCR assays in a timely manner at the sample collection site, thus requiring the transport of collected virus swab samples where the virus itself can rapidly dissolve outside the body, thereby interfering with subsequent testing. Therefore, you need to add virus preservation solutions for storage and transportation, and for different assay purposes you need to use different virus preservation solutions.

Currently, it is mainly divided into inactivated and non-inactivated types. In order to meet different testing requirements and different virus testing laboratory conditions, it is very necessary to use different preservation solutions. So, what is the difference between inactivated and non-inactivated preservation solutions, the following virus sampling tube manufacturers take you to understand it

Inactivated storage solutions: Inactivated storage solutions lyse and inactivate the virus in the sample, thereby depriving the virus of its infectious activity. It effectively prevents secondary operator infection, but it also contains inhibitors that protect the viral nucleic acid from degradation so that subsequent detection by NT-PCR can be performed. And it can be stored at room temperature for relatively long periods of time, thus saving the cost of preserving and transporting viral samples.

Non-inactivated preservation solution: Non-inactivated preservation solution maintains the in vitro activity of the virus as well as the integrity of the antigen and nucleic acid, protects the viral protein tegument from disintegration, and preserves the originality of the viral sample. Extent. In addition to nucleic acid extraction and detection, it can be used for virus culture and isolation.
