Safe COVID-19 sample transport

DNA/RNA Shield: THE solution for COVID sample transport and storage - virus inactivation with no cold chain requirement

Cambridge Bioscience are able to supply a solution that is proven to enable the collection and transport of virus infected samples, at room temperature, with no degradation of the viral RNA. This solution can dramatically improve the efficiency and scalability of the UK’s COVID testing capabilities.

DNA/RNA Shield™ from Zymo Research is a proprietary DNA and RNA stabilisation solution that can be used with standard nasopharyngeal and throat swabs to safely and securely collect suspected COVID infected samples. DNA/RNA Shield is simply added to the collection tube and the sample will be instantly stabilised preserving the genetic integrity and expression profiles of the sample at ambient temperatures whilst deactivating the virus.

DNA/RNA Shield has been tested on a wide range of viruses including the MERS coronavirus and Ebola, has been available for many years and is being used internationally in major centres from Wuhan in China, to Quest Diagnostics in the USA.

This crucial reagent is available right now from our supplier and we, as their exclusive UK distribution partner, are able to source this at a scale of 1000’s litres.

Pathogen inactivation
DNA/RNA Shield has been rigorously tested to ensure its capability to inactive even the toughest of viruses without the need for additional steps, such as heat-treatment, homogenisation, or alcohol sterilisation. In an independent study, the virucidal activity was shown to inactivate murine parvovirus1. DNA/RNA Shield abides by the Center for Disease Control’s (CDC) guidelines for pathogen inactivation2.

Pathogen type Species inactivated
Viruses MERS-coronavirus, Parvovirus, Chikungunya virus, Dengue virus, Ebola virus, Herpes simplex virus-1, Herpes simplex virus-2, Influenza A, Rhinovirus, West Nile virus
Bacteria B. subtilis, E. faecalis, E. coli, L. fermentum, L. monocytogenes, M. tuberculosis, P. aeruginosa, S. enterica, S. aureus, S. pneumoniae, X. fastidiosa
Yeast and eukaryotes C. albicans , C. neoformans , S. cerevisiae , P. malariae
