DNA/RNA Shield reagent

The DNA/RNA Shield™ reagent from Zymo Research is a DNA and RNA stabilisation solution which preserves the genetic integrity and expression profiles of samples at ambient temperatures, whilst completely inactivating infectious agents (viruses, bacteria, fungi and parasites). This unique solution also prevents degradation from freeze-thaw cycling and unexpected freezer failures, allowing ambient temperature shipping.

Available as a 2X concentrate or as a ready to use mix, DNA/RNA Shield is compatible with any custom collection devices.

Benefits of using DNA/RNA Shield
• No reagent removal required prior to nucleic acid purification
• Pathogen inactivation
• RNA stable at room temperature for one month
• DNA stable at room temperature for two years
• RNA and DNA stored at -20C is stable indefinitely

DNA/RNA Shield: complete pathogen inactivation
DNA/RNA Shield has been rigorously tested to ensure its capability to inactive even the toughest of viruses. 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.

DNA/ RNA Shield effectively inactivates pathogens. This includes tough-to-lyse microbes or viruses without the need for additional steps, such as heat-treatment, homogenisation, or alcohol sterilisation. DNA/RNA Shield has been rigorously tested to ensure inactivation of pathogens including:

Bacteria 
B. subtilis, E. faecalis, E. coli, L. fermentum, L. monocytogenes, M. tuberculosis, P. aeruginosa, S. enterica, S. aureus, S. pneumoniae, X. fastidiosa

Viruses 
Parvovirus, Chikungunya virus , Dengue virus, Ebola virus, Herpes simplex virus-1, Herpes simplex virus-2, Influenza A, Rhinovirus, MERS-coronavirus, West Nile virus 

Yeast & eukaryotes 
C. albicans , C. neoformans , S. cerevisiae , P. malariae
