Ambion® 0.1 mM EDTA is a commonly recommended storage solution for RNA samples. 0.1 mM EDTA is in nuclease-free, ultrapure water. It is provided in one bottle of 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. 0.1 mM EDTA 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.
