After nucleic acid collection, specimens are usually not immediately available for PCR testing, so specimen swabs need to be preserved for transport. Since viruses can quickly split in vitro and affect subsequent testing, it is necessary to use disposable viral transport medium tube (VTM tubes) with virus preservation solution to preserve and transport samples.
Single-use VTM kits are usually divided into two types, non-inactivated and inactivated.
It is mainly a modified virus lysis type preservation solution for nucleic acid extraction lysate. It contains high concentration of guanidine salts which can inactivate the virus efficiently and effectively prevent the operator from secondary infection. The inactivated VTM tube also contains Rnase inhibitor, which protects the viral nucleic acid from degradation and enables subsequent detection by NT-PCR. The inactivated viral transport tube allows samples to be stored at room temperature for a relatively long period, saving the cost of preserving and transporting viral samples.
It is a virus maintenance fluid type preservation solution modified mainly based on transport medium. Non-inactivated viral transport media tubes can be used for nucleic acid extraction and detection, as well as for virus culture, isolation, antigen detection, etc. However, after sampling, it is necessary to maintain a strict low temperature for a long time.
