DNA/RNA transport medium for stool samples

Description


DNA/RNA Shield Fecal Collection tubes are designed for the collection and preservation of nucleic acids from stool specimens. 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.

Researchers compared the effects of storage conditions on the microbial composition of a sample. Samples stored in DNA/RNA Shield had overall a bacterial composition similar to frozen samples, while samples stored in RNALater showed bias for certain microbes.

Researchers developed a flexible automated pipeline to process clinically relevant sample-types (biopsies, fecal, vaginal samples, etc.). In comparing many different collection methodologies, including RNALater and AllProtect, they found that DNA/RNA Shield was the best due to its flexibility in sample types that can be stored in the reagent, as well as its compatibility with many downstream processing workflows.

DNA/RNA Shield was compared to RNALater for small RNA sequencing analysis of miRNA in fecal occults. Researchers showed that miRNA markers in samples stored in DNA/RNA Shield were detectable over a 14 day period at room temperature, whereas unprotected or sampled stored in RNALater showed a drop in detection of miRNA over time.

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)
