| R1101-E | DNA/RNA Shield-Fecal Collection Tube – DX | 10 pack |
DNA/RNA Shield Fecal Collection Tubes – DX are specimen receptacle medical devices for molecular-based in vitro diagnostic applications. These fecal collection tubes take a microbial snapshot of a sample while inactivating viruses making samples safe and ready for transport. Samples stored in the these fecal collection tubes are stable at ambient temperature, and can be frozen for longer-term storage. Simply collect a spoonful of the specimen into the stool collection tubes prefilled with preservative and shake vigorously to ensure proper stabilization.

product faq
Q1: Can DNA/RNA Shield be used on extracted DNA and/or RNA?
Yes, extracted nucleic acids are stabilized in DNA/RNA Shield. Prior to downstream applications, clean-up the sample via the appropriate Zymo Research clean-up kit (Genomic DNA Clean and Concentrator (gDCC), DNA Clean and Concentrator (DCC), and RNA Clean and Concentrator (RCC)).
Q2: A white precipitate occurred after thawing frozen samples stored in DNA/RNA Shield, is this normal?
Some components of the reagent (or sample) may have precipitated out of solution during the freeze-thaw process. Once the sample is thawed to ambient temperature, vortex the sample to bring precipitate back into solution. Furthermore, try heating samples in hand or 37°C for 5 minutes and vortex.
Q3: Do I need to homogenize the sample in DNA/RNA Shield prior to storage?
No, tissues do not need to be homogenized.
Q4: How to collect solid tissues in DNA/RNA Shield?
Transfer tissues in to DNA RNA Shield at room temperature, submerge. Tissue can be homogenized or stored frozen prior to homogenization.
Q5: Can I FACS sort directly into DNA/RNA Shield?
Yes, sort directly into DNA/RNA Shield (e.g. Collect 100 µl of FACS sorted cells into minimally 400 µl of DNA/RNA Shield).
Q6: How long can samples be stored frozen in DNA/RNA Shield?
DNA & RNA (<-20°C): Indefinitely
Q7: How long can samples be stored samples in DNA/RNA Shield at ambient temperature?
RNA > 1 month
DNA > 2 years
Q8: What sample types is DNA/RNA Shield suitable for?
DNA/RNA Shield can be used on a wide variety of sample types including cells, tissues, biological fluids (plasma, serum, saliva, urine), and environmental samples (feces, plants, swabs, etc.).

reviews
“We extracted RNA from cells suspended in DNA/RNA Shield with the Direct-zol miniprep set from Zymo (using Trizol). It worked perfect for us.”
– Mariska B. (University of Amsterdam)
“I did an assay using RNA/DNA shield and it works perfect. The product have excellent reproducibility when stored at 4°C for up to a month.”
– Maha AE. (University of Florida)
“We use DNA/RNA shield and it works well with adults mosquitoes, larvae, eggs. We store it at RT for weeks and at -4°C or -20°C for months, never saw any DNA degradation.”
