DNA/RNA Shield™ by Zymo Research

"This solution is fantastic for stabilizing DNA and RNA at room temperature, which is great for sample shipping and taking your time in sample preparation steps. Extra bonus is meeting the CDC inactivating requirements, which allows easier shipping of samples from COVID-19 patients. The Zymo team are also worth so much more than just the product, their tech support are actual people who work in the lab, so they will know the details and can easily ask more technical questions to the person who actually designed the product. I’ve talked to the creator of this solution a few times (Luigi), such as when we wanted to do metabolomics, and he is always clear and helpful. They also optimize products for the user, I often find when benchmarking kits that Qiagen ones take at least twice as long to perform. Would suggest Zymo for all your genetics needs."

"The product preserved my samples until they were ready to be analyzed. This was a game changer because I didn’t need to store them in a freezer, and I didn’t need to ship them in a special container which also saved me money."

"Good and easy to use. The samples resist a lot when in the product."

"I used DNA/RNA shield to maintain the cold-chain. My samples, as diverse as bacteria from biofilm, fecal samples or WWTP bacteria can be stored before extraction. The samples can be kept at room temperature so I can plan my extractions for the most convenient time. The product is easily removed before extraction."

"The DNA/RNA Shield was highly efficient to protect the RNA samples I used in my experiments. The protocol was also very easy to perform. It was definitely worth buying this and I recommend this product highly for other researchers."

"We received a trial kit with 50 tubes. They were used to collect blood samples in South America, where we are currently doing research on malaria and dengue. We have extracted RNA from the tubes with no problem. The RNA yield is superior and of better quality than using filter paper. The best is that researchers in the field do not need a refrigeration system to keep the tubes after blood has been obtained."

"DNA/RNA shield was a very effective method to isolate RNA and DNA from various mouse tissues. The purity of RNA and DNA was very high and we received a high yield from the small amount of tissue we used."

"We are working to collect environmental water samples for microbial community analysis. Our first attempt had us collecting the water samples, trying to keep them cold until we got back to the lab followed by immediate DNA extraction. The day was long, stressful, and unsuccessful. Enter DNA/RNA Shield. This item is designed for being in the field. It is stable at ambient temps, does not require any fancy or complicated procedures, neutralizes pathogens, and got us great results. We simply added the water sample to the DNA/RNA Shield and we were done. We also used Zymo's ZymoBiomics service for this project. Once we had the samples, all we had to do was pack them up and send them in. It was too easy. We got back amazing results from our samples that we could not have gotten in-house. As I was sharing this with a colleague who was working on blood for genomic analysis, she accused me of witchcraft. She is now using this product as well and getting great, easy results."

"The product is easy to use and the instructions are clear. The seller contacted us right after we bought for the first time. The price is affordable. The quality of the product is good and it can be sent to other places without the need of storing it at 4 degrees C. We didn't have any problems with the results and the DNA was as expected as in a fresh sample."
