THE Ambion® RNA Storage Solution is a buffer that provides greater RNA stability than standard 0.1 mM EDTA or TE Buffer. This 1 mM sodium citrate, pH 6.4 +/- 0.2 buffer is provided in one bottle containing 50 mL. The last step in every RNA isolation protocol is to resuspend the purified RNA pellet. After painstakingly isolating the RNA, it is crucial that the pellet be suspended and stored in a safe, RNase-free solution. THE RNA Storage Solution has two features that minimize base hydrolysis of RNA: a low pH, and sodium citrate, which is an efficient chelating agent. THE RNA Storage Solution is compatible with all common RNA applications such as reverse transcription, in vitro transcription, northern analysis, and nuclease protection assays. THE RNA Storage Solution is prepared from the purest reagents available, under scrupulously monitored conditions in a state-of-the-art manufacturing facility. It is then subjected to rigorous quality control procedures to guarantee their purity and performance.
