RNeasy Mini Kit
For purification of up to 100 µg total RNA from cells, tissues, and yeast
The RNeasy Mini Kit provides fast purification of high-quality RNA from cells, tissues, and yeast using silica-membrane RNeasy spin columns with a binding capacity of 100 μg RNA. Tissue samples can be conveniently stabilized using RNAprotect Tissue Reagent or Allprotect Tissue Reagent, and efficiently disrupted using a TissueRuptor or TissueLyser system. RNA purification using the RNeasy Mini Kit can be fully automated on the QIAcube Connect. For smaller and larger samples, the RNeasy Micro Kit (spin-column binding capacity of up to 45 µg RNA), the RNeasy Midi Kit (spin-column binding capacity of 1 mg RNA), and RNeasy Maxi Kit (spin-column binding capacity of 6 mg RNA) are also available.

Product Details
Performance
Total RNA is easily purified with the RNeasy Mini Kit from up to 30 mg animal or human tissues, from 100 to 1 x 107 animal or human cells, or yeast (see table; and figures "RT-PCR of RNA from as few as 100 cells" and "High-quality RNA from a variety of samples").
Principle
The RNeasy Mini Kit allows efficient purification of total RNA from small amounts of starting material. 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.
Procedure
With the RNeasy Mini Kit, total RNA is easily purified from 10 to 1 x 107 animal or human cells, 0.5–30 mg animal or human tissues, and <5 x 107 yeast cells. Samples are first lysed and then homogenized. Ethanol is added to the lysate to provide ideal binding conditions. The lysate is then loaded onto the RNeasy silica membrane (see figure "RNeasy Mini spin column"). RNA binds (up to 100 µg capacity), and all contaminants are efficiently washed away. For certain RNA applications that are sensitive to very small amounts of DNA, the residual amounts of DNA remaining can be removed using a convenient on-column DNase treatment. Pure, concentrated RNA is eluted in 30–100 µl water (see figure "RNeasy Mini procedure"). A variety of special application protocols is also available.
Applications
RNA purified with RNeasy technology has A260/280 ratios of 1.9–2.1 (measured in 10 mM Tris·Cl, pH 7.5) and is ideal for use in all applications. Downstream applications include:
