Can RNAprotect Tissue Reagent be used to store previously isolated RNA?

We do not recommend to store previously isolated RNA in RNAprotect Tissue Reagent, since it will be very difficult to recover isolated RNA from it. Purified RNA can be stored at −30 to −15°C or −90 to −65°C in sterile RNase-free water. Under these conditions, we found no detectable RNA degradation after 1 year of storage.
