Recently, the rebound of Beijing's new crown epidemic has sounded the alarm for our life in the post-epidemic period. The epidemic situation in the United States, Brazil, India, Africa and other regions is also intensifying. The new crown virus will inevitably leave a striking stroke in human history. In order to gain a deeper understanding of this RNA virus, we conducted a brief interview with the company's technology research and development department.
Hubei's new Desheng is a technology company specializing in the production of blood testing related reagents in the Optical Valley United Technology City. At the early stage of the outbreak, it began to invest heavily in the research and development of RNA virus Transport Medias, and eventually produced products approved by many companies.
So we made an appointment and interviewed the engineer Liu responsible for technology research and development. A series of interview questions are as follows:
Viruses and nucleic acids
Q: The company originally made blood test reagents. Why did it decide to make virus Transport Media?
A: The company did start as a blood collection tube reagent, but that is only one of the main series in our products. The company has always produced a series of biochemical detection related reagents such as blood collection tube reagents, biological buffers, and sample tube Transport Medias, and even There are also some emerging reagent materials. Our advantage is R&D synthesis and innovation. And the virus Transport Media is an important part of the virus detection process. The market is in urgent need, and we are doing our best for the society.
Q: The news now says that the nucleic acid test has false negatives. Is this related to the virus Transport Media?
A: There are many cases of false negatives. Instead, the virus Transport Media is to reduce the occurrence of false negatives and increase the accuracy of detection. Because the virus will be quickly lysed in vitro, it is usually not detected in time after sampling. It can keep the original characteristics of the samples during transportation and storage to ensure the accuracy of the detection. Of course, if the virus Transport Media deteriorates or grows bacteria, it will not be able to protect viral proteins or viral RNA.
Q: How do you tell if the virus Transport Media has deteriorated or grown bacteria?
Generally, it can be observed by the naked eye first. Usually, the non-inactivated virus Transport Media is easy to deteriorate or grow bacteria, and the inactivated type is not easy to deteriorate. Deteriorated storage solution is usually uneven in color, accompanied by turbidity or flocs, of course, the normal color is ultimately determined by testing to determine whether it is available.
Through the interview, we learned some common problems of virus Transport Media in the sampling tube. Finally, Engineer Liu also shared some suggestions for avoiding the deterioration of the Transport Media. The main reason is that the temperature is too high during transportation and the air during the packaging process. The contact is contaminated with bacteria and fungi, so be sure to keep strict low temperature and the product container is sealed tightly, especially the non-inactivated Transport Media.
