Before understanding Virus Transport Media, let’s first understand which viruses are made up of. Viruses are composed of a nucleic acid molecule and protein or only protein. Individuals are small and simple in structure. Common epidemic infectious diseases are usually RNA viruses, such as influenza virus, HIV, influenza A virus. Because there is no cell structure, the virus cannot replicate itself, but invades its genes into the host cell, using the latter's replication system to replicate new viruses. After the virus sample is collected, in order to maintain the viability of the virus sample and prolong the survival time of the virus in the sample, the sampling swab will be stored and transported in Virus Transport Media.
Virus Transport Media has two types: inactivated and non-extinguishing. The inactivated Virus Transport Media uses high-concentration guanidine salt to quickly inactivate and preserve respiratory pathogens, making the sample lose infectivity. The inactivated samples can be used with a variety of viral DNA/RNA extraction kits. The M32/M96 nucleic acid extractor can quickly extract nucleic acids. At the same time, it can be used with the respiratory pathogen PCR detection kit to achieve rapid detection, and the specific sensitivity is not affected.
The non-inactivated Virus Transport Media contains Hanks liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer, and amino acids. A combination of multiple antibiotics has anti-bacterial and anti-fungal effects; Bovine Serum Albumin (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; Hanks The neutral environment constructed by the buffer helps increase the survival time of the virus and the stability of infection. The non-inactivated 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 other virus specimens, as well as mycoplasma, ureaplasma, chlamydia and other specimens.
The sudden new crown epidemic has caused serious impacts on many companies. As high schools and junior high school students in major regions resume school, the demand for new crown pneumonia nucleic acid testing is increasing. Virus Transport Media, as one of the indispensable products for nucleic acid testing, has been greatly affected. Major companies are concerned. Since the resumption of work and production, Desheng Technology has been committed to the research and development and production of Virus Transport Media, blood collection tube additives and other products. It has made considerable progress and its products have been well received at home and abroad!
