Virus preservation solution, for us after experiencing the new coronavirus, should not be so unfamiliar with its appearance, because it is important for the detection of nucleic acid viruses.
The recent "Shenzhen epidemic involves 4 mutant strains, the first time the latest notification of the Shenzhen epidemic was found: 9 new positive cases of the current round of the epidemic strains mainly belong to Omicron BA.5 evolutionary branch BF.15!" virus attack, some domestic cities opened the full nucleic acid testing, and virus preservation fluid can find out the hidden culprit.
Because the current detection method of the new coronavirus is still mainly the detection of viral nucleic acid, and virus preservation fluid is a sampling tube within the submerged sampling swab virus specimen of a liquid to protect the virus of the detected material, it is mainly applicable to the new coronavirus, hand, foot and mouth virus, influenza virus and other common viral sample collection preservation transport work, can be used to collect pharyngeal swabs, nasal swabs or specific parts of the tissue samples.
The stored samples can be used for subsequent clinical experiments such as nucleic acid testing or virus culture.
As viruses are parasitic organisms, they cannot survive in vitro after sampling, so if they cannot be detected in time, they need to be preserved in virus preservation solution. In order to protect the safety of the virus detection environment and the safety of the detectors, inactivated virus preservation solution is actually a better choice.
It has already been said that inactivated virus preservation solution can make the virus inactive, how does it come to be detected after losing its activity? The purpose of using inactivated preservation solution is to lyse the nucleic acid, release the nucleic acid and then perform nucleic acid detection by subsequent real-time fluorescence RT-PCR, through which we can determine whether the sample contains the characteristic nucleic acid of the virus, that is, whether it is infected with the virus. The virus has a single structure, which contains only one nucleic acid and protein, so detection of the characteristic nucleic acid detects the virus. Usually after we sample the virus, the sample is not always transported and preserved at the sample collection, so we need to transport and retain the collected virus swab, otherwise the virus nucleic acid will be quickly degraded to detect the nucleic acid, so it is necessary to add preservation solution to the sampling tube to make the virus nucleic acid is not so quickly degraded.
Ltd. produces non-inactivated virus preservation solution compared with other manufacturers on the market, not only adds the Hanks buffer necessary for viruses to build a neutral environment, but also adds bovine serum albumin (BSA) as a protein stabilizer, which protects the protein shell of the virus and makes it less likely to decompose, and obtains good quality DNA/RNA, which can get faster The DNA/RNA obtained is of good quality and can be used to obtain faster detection results, which can complete various virus detection and analysis experiments, such as PCR, qPCR, etc. At the same time, it can save transportation costs and provide free sample delivery services for customers who need it. Technology will not be wrong.
