Why should I use the RNeasy Microarray Tissue Mini Kit when purifying RNA for microarray analysis?

The RNeasy Microarray Tissue Mini Kit significantly speeds up RNA purification. After sample lysis with QIAzol Lysis Reagent, the aqueous phase is directly applied to an RNeasy column, shortening the procedure to as little as 40.minutes. Furthermore, the direct application of the aqueous phase to an RNeasy column allows omission of the alcohol precipitation step, which prevents potential loss of RNA and avoids variable RNA yields, thereby increasing the reproducibility of results.
