What is the function

For virus sample collection, transportation, preservation, etc., for later extraction, extended use.

2 . Difference between inactivated and non-inactivated preservation solution

After virus samples are collected, nucleic acid testing cannot be performed in a timely manner at a general sample collection station, so the collected virus swab samples need to be transported, but the virus itself will decompose immediately outside the body, affecting subsequent examinations. Preservation and transport require participation in virus preservation solutions, and different virus preservation solutions are used depending on the intent of the test. Nowadays, there are mainly two types of preservation solutions, inactivated and non-inactivated, and it is necessary to choose different preservation solutions in order to meet different testing requirements and different laboratory conditions for virus testing.

Inactivating preservation solutions.

Biological preservation fluid b can break down the virus in inactivated samples, so that the virus loses its infectious activity. It effectively prevents secondary infection by operators, but also contains inhibitors that maintain the viral nucleic acid from being broken down, which can then be detected by NT-PCR. In addition, it can be stored at room temperature for a relatively long period of time, which can save the cost of preserving and transporting virus samples.

Non-inactivating preservative solutions.

Biological preservation fluida can maintain the activity of the virus in vitro, the integrity of the antigen and nucleic acid, maintain the shell of the virus protein without decomposition, and maintain the originality of the virus sample to a large extent. In addition to nucleic acid extraction assays, it can also be used for virus culture and isolation.

Biovirus sampling tubes have thickness and leak-proof design to ensure that samples will not leak during transportation. Sampling tubes that comply with WHO rules and biosafety rules.
