The DNA/RNA Shield™ Fecal Collection Tubes (DX) from Zymo Research are CE-IVD certified specimen collection devices for molecular-based, in vitro diagnostic applications. Tubes are pre-filled with DNA/RNA Shield reagent that enables ambient temperature shipping, whilst preserving both DNA and RNA and inactivating pathogens within faecal samples.
Using the scoop attached to the screwcap, faecal samples can be collected directly into the tube pre-filled with DNA/RNA Shield, with no need for reagent removal prior to nucleic acid purification. Samples collected are ready for downstream microbiomic analysis in 16S rRNA gene sequencing, shotgun metagenomic sequencing, arrays, PCR and other sensitive applications.

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
