Stabilize RNA samples at ambient temperature for storage, transport, and day-to-day handling RNA is unstable — and precious. GenTegra RNA stops RNA degradation at the source by stopping RNase activity as soon as it is added to the RNA solution. GenTegra RNA also prevents hydrolysis and oxidation, while freezing merely slows these processes. Your RNA samples are stabilized in both the liquid form for safer handling, and after drying for shipping or long term storage. GenTegra RNA is like insurance against delays when shipping samples. Delays of a few days or even weeks will not destroy your precious samples, which can happen if the delay exhausts the dry ice or ice packs. Start using GenTegra RNA and stop worrying about the quality of your samples. Ongoing ambient temperature experiments show retention of quality for 3.5 years After six months of dry state storage at 25 °C, 37 °C, and 56 °C, samples on GenTegra RNA were kept at ambient temperature (25 °C) for three years, duplicating actual storage conditions. After rehydration, Dried in Dried in Dried in water citrate EDTA these samples still show no degradation and perform identically to frozen controls in downstream 500 bp applications. 250 bp 2% agarose gel of high quality (308 bp) 18S RT-PCR products generated from purified HeLa RNA samples after 3.5 years of mixed temperature, dry state preservation on GenTegra RNA. Initial storage temperatures: lanes 3, 6, and 9 at 25 °C; lanes 4, 7, and 10 at 37 °C; and lanes 5, 8, and 11 at 56 °C. Recovering your sample after storage or shipping is fast and easy. Simply add water to recover 100% of your sample, and it is immediately ready for downstream applications. Long term protection and stability RNA samples stored in the dry state on GenTegra RNA show no degradation after the equivalent of four years of ambient temperature storage1. water citrate RIN Score Agilent Bioanalyzer (RIN) scores for purified HeLa RNA samples after 3.5 years of mixed temperature, dry state preservation on GenTegra RNA. 2% agarose gels of purified HeLa RNA samples in water, citrate, and EDTA solutions stored frozen (controls) or applied to GenTegra RNA, then air-dried and stored at 25 °C, 37 °C, and 56 °C for six months. High Agilent Bioanalyzer (RIN) scores reveal the high quality of samples preserved on GenTegra RNA. Bruskov, VI. Malakhova, LV. Masalimov, ZK. Chernikov, AV.

Protect in solution and dry state GenTegra RNA protects your samples in three ways. In liquid form, it preserves sample integrity for up to 100 hours at 25 °C. When dried, it stabilizes samples for indefinite periods of storage at ambient temperature. And, it provides quantitative integrity of samples through several cycles of drying and rehydration.
