RNeasy Plant Mini Kit

The RNeasy Plant Mini Kit is ideal for isolation of total RNA from a wide variety of plant and fungal samples with sample sizes of 10–100 mg tissue, or 100–1 x 10⁷ cells (see table "Selected samples processed with the RNeasy Plant Mini Kit"). The binding capacity of the spin-columns is up to 100 µg RNA. The typical yield from 100 mg plant tissue is between 25 µg and 65 µg of RNA, although amounts of RNA can vary due to the developmental stage and growth conditions of the samples (see table "Yield from 100 mg tissue").

The purified plant RNA, eluted in 30–100 µl volume, includes viral RNA (see figure "Detection of viruses"). All contaminants, such as polysaccharides, are removed, and the eluted RNA is ready for all downstream applications (see figure "Tissue specificity of histone H4 expression").

The RNeasy Plant Mini Kit provides QIAshredder columns for homogenization and filtration of viscous plant or fungal lysates by microcentrifugation in combination with RNeasy Mini spin columns for RNA purification. RNeasy technology simplifies total RNA isolation by combining the stringency of guanidine-isothiocyanate lysis with the speed and purity of silica-membrane purification. RNeasy Kits provide the highest-quality RNA with minimum copurification of DNA. For certain RNA applications that are sensitive to very small amounts of DNA, the residual amounts of DNA remaining can be removed using convenient on-column DNase treatment during the RNeasy procedure.

RNA purified with RNeasy technology is high-quality and is ideal for use in all applications. Downstream applications include:

Northern, dot, and slot blotting

End-point RT-PCR

Quantitative, real-time RT-PCR

Array analysis

Poly A+ RNA selection
