The DNA/RNA Shield™ Lysis Tubes from Zymo Research ensure sample stability during storage/transport at ambient temperatures, without the need for refrigeration or specialised equipment.
DNA/RNA Shield and BashingBead™ technologies effectively lyse samples and inactivate pathogens (e.g., virus, bacteria). Nucleic acids are preserved at ambient temperature (DNA>1 year; RNA up to 1 month), and samples in DNA/RNA Shield can be frozen (-20/-80°C) for prolonged storage.
Benefits of using the DNA/RNA Shield Lysis Tubes
• No reagent removal required prior to nucleic acid purification
• Tube prefilled with ultra-high density Bashingbeads™ for homogenisation
• RNA stable at room temperature for one month
• DNA stable at room temperature for two years
• Available with/without nylon swab

DNA/RNA Shield can be added to frozen or fresh samples to prevent degradation
Left: High-quality RNA from blood stored in DNA/RNA Shield that was freeze-thawed from -80°C to room temperature. Whole blood samples +/- DNA/RNA Shield were subjected to > 2 freeze thaw cycles. Total RNA was subsequently purified using the Quick-RNA™ Whole Blood Miniprep Kit. Right: High-quality DNA from stool stored in DNA/RNA Shield after up to 10 freeze-thaw cycles. Microbial composition profiling via 16S rRNA gene targeted sequencing.
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:
B. subtilis, E. faecalis, E. coli, L. fermentum, L. monocytogenes, M. tuberculosis, P. aeruginosa, S. enterica, S. aureus, S. pneumoniae, X. fastidiosa
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
