The target of new coronavirus nucleic acid detection is the nucleic acid gene fragment inside the virus. Nucleic acid virus transport media protects viral nucleic acid from rapid degradation in vitro, so as to facilitate nucleic acid sequence amplification for detection purposes. Mainly divided into two categories: inactivated and non-inactivated. Disposable virus sampling tubes are usually divided into two types, non-inactivated type and inactivated type. Different types need to be selected for different detection purposes. So how to choose the two virus sampling tubes

inactivated virus transport media
Inactivated virus transport media is a preservation solution based on nucleic acid extraction lysate. The main components are balanced salts, chelating agents, guanidine salts, and surfactants. There are two types of inactivated preservation solutions: one is the guanidine salt-containing type, which can quickly and efficiently denature proteins, lyse cells to release nucleic acids, eliminate RNases, stabilize viral nucleic acids, and inactivate viruses. Effect. The other is the guanidine-free type, which contains surfactants and does not split the capsid protein on the surface of the virus, maintaining the integrity of the virus, and the virus is not easy to survive.
Non-inactivated virus transport media
The non-inactivated virus transport media can retain the protein coat of the virus and the virus nucleic acid at the same time, and maintain the originality of the virus sample to the greatest extent. In addition to being used for virus nucleic acid detection, it can also be used for virus culture, etc. However, because the virus has not been inactivated, there is a risk of infection if the operation is wrong.
The Work Manual for Viral Nucleic Acid Detection (Trial Version 2) clearly states that "for population screening, selection of sampling tubes with virus inactivation functions, such as guanidine salts (guanidine isothiocyanate or guanidine hydrochloride, etc.) or surfactants, should be selected. For rapid testing in fever clinics or emergency departments, the sampling tube shall be determined according to the requirements of the nucleic acid detection reagents used.”
Regardless of whether it is an inactivated type or a non-inactivated type, the virus sampling tube before sampling must be strictly inactivated and sterilized to ensure that there are no other microorganisms in the tube, which may cause the virus to decompose or other influences after sampling and cause false detection. After swab sampling, if a collection tool or preservation solution of poor quality is used, it will affect the subsequent test results and even cause misdiagnosis. Therefore, you must choose a virus sampling tube produced by a professionally qualified manufacturer.
Desheng is one of the first companies to invest in the R&D and production of virus preservation solutions since the resumption of work in 2020. At that time, there were not too many companies joining the ranks of virus transport media. With the increase in the demand for nucleic acid testing, a number of companies emerged. Another batch of enterprises that have been put into production, no matter at the beginning or now, Desheng always remembers to give back to customers with good quality. Only when the quality is guaranteed, can we gain the trust of more customers. At present, it has obtained the first-class medical device production. For the record certificate, new customers can send samples for free. Large quantities have more preferential prices. Welcome to consult and buy!
