Introduction of virus preservation solution in sampling tube

Virus sampling swab is a commonly used virus sampling method, which can be used for rapid detection of viral diseases. However, not every sample collection site can carry out PCR detection, so the collected virus swab samples need to be transported. So swab virus preservation solution came into being.

Virus is composed of a nucleic acid molecule and protein or only protein. It is small in size and simple in structure. The common epidemic disease is RNA virus. Such as influenza virus, HIV, influenza A virus. Because there is no cell structure, the virus can not replicate itself. Instead, it invades the host cell and replicates the new virus with the help of the latter's replication system. After the collection of virus samples, in order to maintain the activity of the virus sample wood and prolong the survival time of the virus in the sample, the sampling swabs will be stored and transported in the preservation solution.

The virus preservation solution (inactivated type) can quickly inactivate and preserve respiratory pathogens with high concentration of boat salt, which makes the samples lose infectivity. The inactivated samples can be used for DNA / RNA extraction test kit. M32 / M96 nucleic acid extractor was used to extract nucleic acid rapidly. At the same time, PCR detection kit was used to detect respiratory pathogens. The specificity and sensitivity were not affected.
