Due to the impact of the epidemic, the topic of novel coronavirus has become our daily topic. Recently, Wuhan has implemented the national nucleic acid test. When it comes to nucleic acid detection, we will talk about the virus transport media developed and produced by Desheng. What role does it play in nucleic acid detection?
At present, there are two types of virus transport media: inactivated and activated type.
Virus sampling swab is a common method of virus sampling combined with PCR, which can be used for rapid detection of viral diseases. However, not every sample collection place can carry out PCR detection, so it is necessary to transport the collected virus swab samples, so the swab virus transport media came into being.
Desheng’s virus transport media
For different detection purposes, different virus transport medias need to be used. At present, the two widely used transport media have their own characteristics. In order to meet the different requirements of detection and different laboratory conditions of virus detection, it is necessary to sample different transport media.
Virus transport media (inactivated type) can be used to inactivate and preserve respiratory pathogens quickly by using lysate, which makes the samples lose infectivity. The inactivated samples can be matched with a variety of virus DNA/RNA extraction kits, M32/M96 nucleic acid extractor for rapid extraction of nucleic acid, and the respiratory pathogen PCR detection kit for rapid detection. The specificity sensitivity is not affected.
Virus transport media (activated type) contains Hanks liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids. The combination of multiple antibiotics has the effect of anti bacteria and anti fungus; BSA, as a protein stabilizer, can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus; the neutral environment constructed by Hanks buffer helps to increase the survival time and infection stability of the virus. The activated virus transport media is usually used for the collection and transportation of clinical influenza, avian influenza (such as H7N9), hand-foot-mouth disease, measles and mycoplasma, Ureaplasma and chlamydia.
Desheng technology has been committed to the R&D and production of virus transport media, carbomer and other products since the resumption of the epidemic, and has achieved a breakthrough victory. The affirmation of customers after use is a great encouragement to us! We will continue to do our products well, not for the immediate interests, only for better development and customer trust.
