DNA/RNA Shield Fecal Collection Tube - DX

Description

DNA/RNA Shield Fecal Collection Tubes - DX are specimen receptacle medical devices for molecular-based in vitro diagnostic applications. These stool collection tubes take a microbial snapshot of a sample while inactivating viruses making samples safe and ready for transport. Samples stored in the these stool 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.


Applicable For Next-Generation Sequencing, qPCR, microarray
Device Specs 20 x 76 mm screw cap tube prefilled with DNA/RNA Shield (9mL). Spoon attached to screwcap.
Device Storage RNA: Ambient temperature (4°C-25°C) > 1 month
DNA: Ambient temperature (4°C-25°C) > 2 years
DNA & RNA: Frozen (< -20°C): Indefinitely
Registration Status CE-IVD certified
Sample Collection 1g or 1mL stool sample
Sample Source Stool, soil, environmental samples

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.).




“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.”

- Umberto P. (University of Pavia)
