RNAstable® and RNAstable® LD allows you to preserve and ship your total RNA, mRNA, and miRNA for up to 12 years at ambient temperatures*. They provide a cost-effective, eco-friendly solution to freezer crawl and lab space management. Moreover, they eliminate sample loss due to freeze/thaw cycles. When you are ready to use your RNA samples, you can fully recover them in minutes without any additional purification steps.
RNAstable is available in two convenient formats:
RNAstable: provided pre-dried in 1.5 ml microfuge tubes and 96-well plates to which hydrated RNA can be added.
RNAstable LD: a liquid reagent which can be added directly to RNA samples in your own tubes, multi-well plates, or other containers
Figure 1: RNAstable protects total RNA, mRNA, miRNA. Samples can be safely stored for 12 years at ambient temperature and protected from degradation.

Figure 3: (A) Aliquots of total RNA were stored for 29months at either -80°C or at room temperature protected in RNAstable or unprotected. RNA integrity was assessed using agarose gel electrophoresis and bioanalyzer analysis (e.g. RIN score). (B) Aliquots of the stored samples were quantified using the 18S rRNA gene in a One-Step RT-PCR reaction. Three samples were amplified for each storage condition and the results from the 9 reactions are overlaid on the graph. (C) Recovery levels (pg) for total RNA stored under identical conditions.
Pre-dried in 1.5 ml microfuge tubes and 96-well plates (RNAstable)
Liquid aliquots of 2 ml and 10 ml (RNAstable LD)
Application volume: 100μl
Application amount: 0.01 to 100µg
Drying time: Overnight (laminar flow hood); 0.5 to 1.5 hours with vacuum concentrator system (speedVac®)
Recovery volume: 10 to 100μl
DNA storage at room temperature: 12 years accelerated aging; 3.5 years “real time”
Touch the yellow matrix with an RNAase-free pipette tip. If yellow does not stick to the tip, then RNAstable is completely dry. If yellow sticks to the tip, then RNAstable® is not completely dry. Allow sample to continue drying.
