Introduction of Virus Transport Media in sampling tube

Virus sampling swabs are commonly used virus sampling methods combined with PCR and can be used for rapid detection of viral diseases. However, not every sample collection site can perform PCR detection, so it is necessary to transport the collected virus swab samples, so the swab Virus Transport Media came into being.

The virus is composed of a nucleic acid molecule and protein or only protein. The individual is small and simple in structure. Common epidemic infectious diseases are usually RNA viruses, such as influenza virus, HIV, and 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 the preservation solution.

The Virus Transport Media (inactivated type) 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 without affecting the specific sensitivity.

The Virus Transport Media has many functions:

1. The operation is simple and does not require liquid preparation. The system contains high-efficiency virus lysis solution, which can inactivate the virus immediately after sampling, effectively preventing the risk of secondary infection.

2. Contains nucleic acid Rnase enzyme inhibitor to maximize the protection of viral nucleic acid from being stable and not degraded, and greatly improve the efficiency of nucleic acid extraction.

3. The product can be stored at room temperature for 12 months before sampling, and the sample can be stored at room temperature for one week after sampling. The airtightness is good, which is convenient for storage and transportation and saves transportation costs.

In addition to the above inactivated Virus Transport Medias, there are also non-inactivated Virus Transport Medias, which contain Hanks liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers 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.

Desheng Technology has been committed to the research of sample collection and in vitro diagnosis and the production and sales of related raw materials since 2005. Blood collection tube additives, Virus Transport Medias, biological buffers and other products have been well received at home and abroad!
