When the epidemic is waiting for an opportunity again, to quickly control the spread of the virus, nucleic acid testing has become the only way to go, and it has also attracted attention from all walks of life. However, there are many factors that affect the results of nucleic acid testing, including sample collection location, collection method, storage and transportation process, nucleic acid extraction operation, and so on. Among them, the stability of the sample is a key link. How to quickly inactivate the virus and protect the viral nucleic acid from being degraded, maintaining the stability of the virus sample storage solution has become a top priority. Step 1: Break the shell and eliminate the "combat power" Like other RNA viruses, the results of the new coronavirus are simply composed of a protein shell wrapped in single-stranded nucleic acid-RNA. We can simply think of the RNA of the virus as the "brain" that gives orders, and the protein is the "limbs" that execute orders. The new coronavirus infects the human body and reproduces and causes symptoms. This process is mainly completed by the biologically active protein structure outside the virus. The inactivated virus preservation solution is mainly the virus modified by the nucleic acid extraction lysis solution; it is a powerful protein denaturant that can quickly dissolve the protein and cause the virus structure to be broken. When the clinical sample with the new coronavirus is mixed with the preservation solution, the virus in the sample is affected by the lysis solution, and the protein shell is quickly destroyed, and this damage is irreversible. At this time, the virus has lost its evil "minions" and no longer has the ability to infect people, thus ensuring the safety of contacts during sample transportation and processing. Step 2: Inhibit enzyme activity and escort the "ID card" After the shell is lysed, the RNA of the new coronavirus is free in the preservation solution. As a single-stranded macromolecule, the stability of RNA is not as immobile as double-stranded DNA. The RNase that exists everywhere in the natural environment is the culprit that causes RNA to hydrolyze and break. Therefore, it is generally considered that the viral RNA that has lost its outer shell protection is In addition to the inactivated virus storage solution, the virus preservation solution produced by Desheng also has a non-inactivated virus storage solution. It retains the protein coat of the virus and the viral nucleic acid DNA or RNA at the same time, so that the virus has the integrity of the protein epitope and nucleic acid in vitro. Of course, there is a certain risk of infectivity when operating errors. Long-term storage after sampling needs to keep strictly low temperature. Regardless of the virus preservation solution, we need to strictly operate, store or transport in accordance with the requirements when using it.

The disposable virus sampling tube/Virus Transport Medium(VTM) is suitable for nucleic acid extraction of SARS-CoV-2 virus, various influenza viruses, avian influenza viruses, rubella, swine fever and other virus samples. The disposable virus sampling tube/Virus Transport Medium(VTM) is suitable for nucleic acid extraction of SARS-CoV-2 virus, various influenza viruses, avian influenza viruses, rubella, swine fever and other virus samples. It is also suitable for the collection and transportation of specimens of Chlamydia, Mycoplasma, and Mycoplasma Arthroplasma. Samples are usually collected from the mouth, throat, nasal cavity, and anus. Sampling tube: The tube body and tube cover are made of polypropylene, which will not deform at high temperature and high pressure (121C, 15min), and will not become brittle at low temperature (196C). Resistant to static extrusion and dynamic impact. The bottom tapered design is resistant to centrifugation and vibration. Built-in sample preservation solution is used for sample preservation to prevent leakage. Sample preservation solution: Functioned with virus lysis solution and virus nucleic acid preservation solution. The virus lysate realizes the inactivation of the virus in the sample and reduces the risk of secondary infection. The unique protection system can prevent nucleic acid from being degraded and improve the accuracy of downstream detection. The sample has a wide adaptability and can be used for the collection, preservation and transportation of various swabs. Sampling swabs: sampling swabs are flocking sampling heads, which are non-toxic to cells and viruses, and do not contain RNase, which can greatly increase the collection and release of virus samples , ensure the accuracy of PCR detection results. The plastic rod is made of ABS, with a unique molded breaking point design, and there is no tiny debris during the breaking process. Features: 1.More collection and release:nylon flocked swabs provide optimum specimen collection because of their ability to collect more specimen at the collection site and to more rapidly release the entire samples specime 2. High safety factor: it can lyse pathogens, inactivate viruses, and reduce the risk of secondary infection. 3. Stable nucleic acid: a unique protection system that can prevent nucleic acid from being degraded and improve the accuracy of downstream detection. 4. Wide sample adaptability: it can be used for the collection, preservation and transportation of various swabs,Including oral swabs, throat swabs, nasal swabs, vaginal swabs and so on.
With the recurrence of asymptomatic, nucleic acid testing cannot be stopped for a moment. This is not only a protection for everyone, but also a protection for yourself. Speaking of nucleic acid testing, we have to bring up our virus sampling tube again. Its choice also plays a key role. Why use a virus sampling tube? Virus detection is different from conventional biochemical detection. The virus itself is a simple microorganism that must be parasitic in living cells. After sampling, the virus leaves the host cell, and its protein shell and nucleic acid will be quickly degraded in the sampling tube, so the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, and it is easy to cause false negatives. What are the requirements for an excellent virus sampling tube? 1. In terms of sample effectiveness: The non-inactivated virus preservation solution must maintain the activity of the pathogen's infectious agent. Preferably, it can preserve the activity of the virus at room temperature. The inactivated virus preservation solution needs to inactivate the virus but maintain the nucleic acid of the virus to meet the time from sample sampling to laboratory testing. It is necessary to limit and prevent the reproduction of symbiotic microorganisms to ensure the reliability of diagnostic tests. 2. In terms of safety: Because the virus sampling tubes are basically all infectious substances, and some are highly pathogenic infectious substances, the requirements for packaging containers are very strict, and they need to meet safety and ensure that liquids do not leak during transportation. . So what is the virus preservation solution? Under what circumstances do I need to use a virus preservation solution? The virus preservation solution is a protective liquid medium added to the virus sampling tube to protect the sample after the nasopharyngeal swab is sampled. Normally, nucleic acid PCR cannot be directly performed at the sample collection site during nucleic acid detection. If the sample collected by the swab needs to be transferred and transported, it is necessary to add a virus preservation solution. Why is the virus preservation solution divided into inactivated and non-inactivated? After the virus samples are collected, there is usually no way to test in time at the sample sampling site, so the collected virus swab samples need to be transported, and the virus itself will be quickly lysed outside the body and affect subsequent testing, so when storing and transporting , You need to add a virus preservation solution. For different detection purposes, you need to use different virus preservation solutions and different virus detection experimental conditions, so it is divided into two types of preservation solutions, inactivated and non-inactivated. There are no other microorganisms, causing the virus to decompose after sampling or other influences causing false detections.
