Figure 1: Streamlined workflow from samples protected by DNA/RNA Shield TM followed by purification by Zymo Research DNA and RNA extraction kits.



Figure 2: The total RNA profile is stabilized from freeze-thaw in whole blood samples protected by DNA/RNA Shield. Whole blood samples +/- DNA/RNA Shield were subjected to > 2 freeze thaw cycles. Total RNA was subsequently purified using the Quick-RNA™ Whole Blood kit and analyzed by TapeStation.




Figure 3: DNA and RNA in blood samples is effectively stabilized in DNA/ RNA Shield at ambient temperature over time. Graphs show (RT)qPCR results from RNA isolated from blood samples stored with DNA/ RNA Shield at various time points for various common targets. Samples ran in quadruplicate.


Figure 4: Microbial composition of stool samples preserved by DNA/RNA Shield versus samples left unprotected. Microbial composition (indicated by different colors) of stool samples were stored over time at ambient temperature with and without protection by DNA/RNA Shield. DNA was extracted with ZymoBIOMICS® DNA Miniprep Kit and then subjected to 16S rRNA targeted sequencing. Want to try it out for yourself? Click here to request a sample of DNA/RNA Shield.
