Description
DNA/RNA Shield Lysis and Collection tubes are microbial lysis tubes and bead beating tubes designed for the streamlined collection, transport, and processing of biological specimen. The microbial lysis tubes and bead beating tubes are pre-filled with DNA/RNA Shield and a lysis matrix tailored for tough-to-lyse- sample inputs from tissue to microbial samples. Collected samples do not require additional handling for processing and are ready for homogenization. Bead sizes include 0.5mm & 0.1mm (R1103 and R1104) and 2.0mm (R1105).

Product FAQ
Q1: 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.).
Q2: 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)).
Q3: How long can samples be stored samples in DNA/RNA Shield at ambient temperature?
RNA > 1 month
DNA > 2 years
Q4: How long can samples be stored frozen in DNA/RNA Shield?
DNA & RNA (<-20°C): Indefinitely
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: 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.
Q7: Do I need to homogenize the sample in DNA/RNA Shield prior to storage?
No, tissues do not need to be homogenized.
Q8: 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.

Reviews
“I’m a Zymo fan! DNA/RNA Shield is a great product. It works great on my precious samples. I trust Zymo Research products and they have great tech support!!”
– Laura T. (USDA)
“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)
“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 extracted RNA from cells suspended in DNA/RNA Shield with the Direct-zol miniprep set from Zymo (using Trizol). It worked perfect for us.”
