What is inactivated virus transport medium? 3 advantages of the preserving fluid

Virus transport media is one of the primary tools for COVID-19 nucleic acid testing. Only by preserving the collected samples in virus transport medium can the stability of the virus be maintained, thus helping the orderly execution of nucleic acid testing.

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.
