Recently, the disposable virus transport media developed and produced by Huachenyang has obtained the FDA 510K certification in the United States for its excellent preservation performance and high product stability. After the CE, TGA, EUA, MDEL, MHRA, and ISO13485:2016 certifications, Huachenyang has obtained the FDA 510K certification, which is a highly prestigious international certification.

Huachenyang is brave enough to break the monopoly of peer brands and the market and to keep pace with the big brands in the field of in vitro diagnostic sampling in terms of qualification and technology.

Huachenyang Disposable Virus Transport Media Tube

• Huachenyang single-use virus transport medium of the tube body texture is PP (polypropylene), which can withstand -197 ℃. Low temperature does not break, and high pressure at 125 ℃ high temperature does not deform.
• The cap is made of PE (high-density polyethylene), which ensures a close combination with the tube’s body. The flare design inside the cap solves the phenomenon of liquid leakage during transportation.
• Independent packaging, easy to use.
• The source manufacturers, the stock is sent in seconds.

Huachenyang disposable virus transport media and sampling swabs constitute a component suitable for the collection and transfer preservation of clinical COVID-19 virus, influenza, avian influenza, hand, foot, and mouth disease, measles, and other virus samples. Virus transport media tubes with different transport media can constitute different types of sample collection and transport components, which can be applied in a variety of scenarios.

The virus preservation solution is mainly divided into inactivated and non-inactivated types, and today we mainly analyze the advantages of inactivated virus transport media.

What is inactivated virus transport medium?

Inactivated virus transfer medium is mainly used for the inactivation of clinical novel coronavirus, influenza virus, avian influenza virus, hand, foot and mouth virus, measles virus, norovirus, rotavirus and other virus specimens, as well as the transfer of virus nucleic acids. It is compatible with various virus nucleic acid extraction reagent kits available in the market, allowing seamless interface with downstream nucleic acid extraction. Virus sampling tubes allow safe transfer of viruses, chlamydia and mycoplasma for further studies including classical cell culture methods, diagnostic tests and molecular biology methods.

Features of inactivated virus transport medium

1. High safety

Virus lysis type buffer, containing a variety of virus inactivation components, efficient inactivation of the virus can ensure the safety of transport and testing personnel.

Contains highly efficient virus lysis solution, inactivating the virus immediately after sampling, effectively preventing the risk of secondary infection.

2. High stability

The preservation solution contains RNase inhibitor, which can ensure the integrity of nucleic acid and prevent false negative results.

After sampling, it does not need to be stored at 2~8℃ for transportation, and storage at room temperature for 48 hours does not affect the quantitative results of nucleic acid.

Viruses can be stored at room temperature for 7 days and still detect nucleic acid in positive samples, which saves the cost of storage and transportation of virus samples.

The product can be stored at room temperature for 12 months before sampling and one week after sampling, which is airtight, easy to store and transport, and can save transportation costs.

3. High Convenience

Inactivated virus preservation solution can rapidly inactivate respiratory pathogens, so that the specimen loses infectivity. The inactivated samples can be used with a variety of viral DNA and RNA extraction kits for rapid nucleic acid extraction, as well as with respiratory pathogens PCR detection kits to achieve rapid detection, specificity and sensitivity are not affected.

There is also a non-inactivated virus preservation solution, which is based on Hanks solution, fungal antibiotics, BSA, cryoprotectants, biological buffers, amino acids and other components.

The use of high-capacity virus sampling tubes that can hold 5 or 10 swab samples can significantly reduce testing costs and improve testing efficiency.

For different testing purposes and different testing requirements as well as different virus testing laboratory conditions, different virus sampling tubes may be required.

Inactivated Virus Transport Media

Mainly nucleic acid extraction lysate modified virus lysis type preservation solution. The high concentration of guanidine salt can inactivate the virus efficiently and effectively prevent secondary infection by the operator, while the Rnase inhibitor inside protects the viral nucleic acid from degradation, thus allowing subsequent detection by NT-PCR. The samples can be stored at room temperature for a relatively long time after being deposited in the inactivated virus transport medium, which saves the cost of preserving and transporting the virus samples.

Non-inactivated Virus Transport Media

It is mainly a virus maintenance fluid type preservation solution modified on the basis of transport medium. It can maintain the activity of virus in vitro and the integrity of antigen and nucleic acid, protect the virus protein shell from decomposition, and maintain the originality of virus samples to a greater extent. In addition to nucleic acid extraction and testing, a non-inactivated virus transport media can also be used for virus culture, isolation, and antigen detection, etc. However, strict low-temperature conditions need to be maintained for prolonged storage after sampling.

Summary

Different types of virus transport media are suitable for different situations. However, it is important to note that whether inactivated or non-inactivated virus preservation solution, the virus sampling tube must be strictly inactivated and sterilized before sampling to ensure that there are no other microorganisms in the tube, otherwise it may lead to virus decomposition or other conditions that may result in false detection. Only the use of qualified collection tools and sample preservation tools can minimize false diagnoses.
