Virus preservation fluid, for many small partners, this term is new, but I do not know that it has important significance for the detection of various viruses, the new coronavirus to human torture enough, in the face of a large number of students to put into the normal life track, many places began to focus on the detection of new coronavirus, in which virus preservation fluid plays a very important role.
At present, the new coronavirus detection method is still mainly for the detection of viral nucleic acid, and virus preservation fluid is a sampling tube submerged in a 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 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, and 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, after losing the activity is how to carry out the detection? The purpose of using inactivated preservation solution is to lyse the nucleic acid, release the nucleic acid and then carry out 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 and the nucleic acid can not be detected, so it is necessary to add preservation solution to the sampling tube to make the virus nucleic acid is not so quickly degraded.
Compared with other manufacturers in the market, Shenzhen Medeco's non-inactivated virus preservation solution not only adds Hanks buffer necessary for viruses to build a neutral environment, but also adds bovine serum albumin (BSA) as a protein stabilizer, which can protect the protein shell of viruses and make them less prone to decomposition, and obtains good quality DNA/RNA and faster detection results, which can complete various Virus detection and analysis experiments, such as PCR, qPCR, etc., while saving transportation costs, customers with demand can provide free sample delivery and other services, Medico has always believed that as long as it has always insisted on good products, so that it can meet the needs of customers to the maximum extent, and finally can certainly surprise customers after repeatedly comparing manufacturers, and found that choosing Medico is not wrong.
