COVID-19: Viral Transport Medium (VTM) for diagnosis
Inspection principle
The inactivated preservation solution contains protein denaturants, nuclease inhibitors, pH buffers and other components, which can lyse cells and release nucleic acids while avoiding nucleic acid degradation. Scientists collect samples with inactivated preservation solutions for molecular testing.
Features
1. Ensure the integrity of DNA&RNA during storage.
2. Put it at room temperature for a few minutes to inactivate pathogens such as viruses and bacteria, prevent secondary infection, and ensure the safety of transportation and testing personnel.
3. It can inhibit the growth of various viruses or bacteria, kill various infectious factors, and realize the safe transportation of infectious samples.
4.
5. Heating the sample in the preservation solution at 56°C for 2 hours will not affect the integrity of the nucleic acid, which is convenient for inactivating the suspected pathogen outside the sampling tube.
Non-inactivated viral transport medium
Product Specifications
2.0ml, 3.0ml, 4.0ml, 5.0ml, 6.0ml.
Inspection principle
A virus maintenance liquid type preservation solution improved based on the transport medium.
The activity of the virus in vitro and the integrity of antigens and nucleic acids.
It contains Hanks liquid, etc., which protects the viral protein.
And maintains the originality of the virus sample to a large extent.
In addition to nucleic acid extraction and detection, experimenters can also use this preservation solution for virus culture, isolation and antigen detection.
Different types of preservation solutions have their advantages and disadvantages according to different situations.
But it should be noted that whether it is an inactivated type or a non-inactivated type, the virus sampling tube before sampling must be strictly inactivated and sterilized to ensure that the tube is inactivated. There are no other microorganisms that could cause false detections due to viral breakdown or other influences after sampling.
After flocked swab sampling, if a collection tool or preservation solution of poor quality is used, it will affect the subsequent test results and even cause false positives for misdiagnosis.
Therefore, it is recommended to use a virus preservation solution of good quality.
