What is the disposable virus sampling tube ?
Since the outbreak of the epidemic Covid-19, nucleic acid testing has become more and more familiar to us.
After nucleic acid collection, usually the specimens cannot be tested by PCR immediately, and the swab samples collected with the specimens often need to be transported, and the virus itself will soon break apart in vitro and affect subsequent detection, so during storage and transportation, it is necessary to add virus preservation solution for preservation, this is a disposable virus sampling tube.
The virus sampling tube liquid is also called virus preservation solution, which is non-toxic. It can denature the protein of fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel. The virus preservation solution in the virus sampling tube is usually divided into two types, namely inactivated type and non-inactivated type:
1. Inactivated type:
The color of the inactivated preservation solution is usually red and white, and a few manufacturers use purple. The inactivated preservation solution is colored, usually to make it easier to observe whether the preservation solution leaks, and to make it easier to observe the liquid level when the laboratory draws the preservation solution after sampling.
The inactivated virus preservation solution is mainly a virus lysis type preservation solution improved by nucleic acid extraction lysis solution. The liquid contains a high concentration of lysis salt, which can quickly and efficiently lysis and inactivate the viral protein in the sample to be tested, which can effectively prevent infection. It also contains an Rnase enzyme inhibitor, which can protect the viral nucleic acid from being degraded. The subsequent RT-PCR experiment can make a diagnosis as long as the viral nucleic acid can be detected. And it can be stored at room temperature for a relatively long time.
2. Non-inactivated type:
Non-inactivated preservation solution is usually red. When the preservation solution deteriorates, its pH will change, and it is easy to identify whether the preservation solution has deteriorated. The non-inactivated virus preservation solution is mainly a virus maintenance solution improved on the basis of the transport medium, which can protect the protein coat of the virus and the viral nucleic acid DNA or RNA, so that the virus has a complete protein epitope and nucleic acid in vitro. There is a certain risk of infection when the operation is wrong. It is necessary to keep strictly low temperature for long-term storage after sampling.
Note
Disposable virus sampling tubes are used for in vitro diagnosis and cannot be used for internal or external use by humans or animals. If swallowed, it can cause serious events; it is irritating to eyes and skin, if splashed into eyes, rinse with water.
