How should RNeasy Kits be stored and how long are they stable?

RNeasy Mini, Midi and Maxi Kits should be stored dry at room temperature (15 to 25°C). The RNeasy MinElute Spin Columns of the RNeasy Micro Kit and RNeasy MinElute Cleanup Kit should be stored at 4°C. RNeasy Kits are stable for at least 9 months under these conditions.
