Viral Transport Medium (VTM), is used to transfer virus specimens after sample collection. The solution acts as a chemical preservative and allows safe transport to the laboratory and a reliable analysis thereafter.
Since a virus is particularly prone to degradation, special preservation methods are needed. Further, due to the current situation with COVID, the demand for virus preservation for testing is very high and conventional cooling methods (e.g. liquid nitrogen) are not viable.
Capricorn Scientific, a German manufacturer of cell culture products, has developed a universal Viral Transport Medium (VTM), which is offered in bulk for local assembly of Viral Transport Medium Kits.
Viral Transport Medium (VTM) is a preservative solution that allows the safe transfer of viruses, chlamydiae, and mycoplasma for further research and analytics. It is suitable for several applications including classical cell culture methods, diagnostic testing, as well as molecular biology techniques (including PCR). The special formulation ensures the best possible recovery of the samples and the addition of antibiotics inhibits the contaminating growth of bacteria and fungi.
The product is provided as bulk liquid media for use in further processes, e.g. filling into smaller sample tubes.
Inadequate or inappropriate specimen collection, storage, and transport will likely yield false test results. Training in specimen collection is highly recommended due to the importance of specimen quality.
The shelf-life of VTM is 12 months from the manufacture date when stored at +2 °C to +8 °C and 3 months when stored at +15 °C to +25 °C.
We recommend you do not freeze the medium and store it protected from light.
Our Viral Transport Medium is based on Hanks Balanced Salt Solution (HBSS) with Calcium and Magnesium and contains heat-inactivated Fetal Bovine Serum, Gentamicin, and Amphotericin B.
This formulation is according to the WHO and CDC recommendations.
All specimens can be stored at +2 °C to +8 °C for up to 72 hours after collection.
If a delay in extraction is expected, we recommend that you store specimens at -70 °C or lower.
Specimens must be packaged, shipped, and transported according to the current edition of the International Air Transport Association (IATA) Dangerous Goods Regulation.
We recommend that you store specimens at +2 °C to +8 °C and ship overnight on ice pack. If a specimen is frozen at -70 °C or lower, ship overnight on dry ice.
