Product Details

RNeasy Plus Kits are next generation QIAGEN RNA extraction kits, combining high-quality RNA purification with effective gDNA removal with unique gDNA Eliminator columns or plates. Total RNA of high purity and yield is obtained from a wide range of cultured cells and easy-to-lyse tissues. The RNeasy Plus Micro Kit is specially designed for limited amounts of samples and isolates up to 45 µg pure total RNA The RNeasy Plus Mini Kit purifies up to 100 µg total RNA (>200 nt) from a single extraction with efficient gDNA removal. Both kits can be automated on the QIAcube Connect and samples can be conveniently stabilized using RNAprotect Tissue Reagent or Allprotect Tissue Reagent and efficiently disrupted using a TissueRuptor II or TissueLyser II or LT system (available separately). The RNeasy Plus 96 Kit is for high-throughput purification of total RNA from cultured cells grown in 96-well plates. For optimal results it is recommended to use this product together with the QIAvac 96 System.

RNeasy Plus Mini standard protocols can also be executed using the TRACKMAN Connected system, paired with PIPETMAN M Connected pipettes, both from Gilson. The TRACKMAN Connected system guides researchers through the RNeasy Plus Mini protocols while automatically adjusting the Bluetooth-enabled PIPETMAN M Connected pipette settings. Each step of the protocol execution is recorded to accelerate reporting by generating a comprehensive run report. Download more information.

Performance

RNA extraction from cells and tissues with RNeasy Plus Micro and Mini Kits allows high, reproducible RNA yields and efficient genomic DNA elimination for sensitive applications (see figures “ Effective cell genomic DNA removal”, “ Effective tissue genomic DNA removal”, " High, reproducible RNA yields", and “ Array-ready RNA”). Total RNA with Agilent RIN values of close to 10 is routinely obtained from tissues and cultured cells.

RNeasy Plus Micro and Mini Kits also provide an enrichment for mRNA since most RNAs <200 nucleotides (such as rRNAs and tRNAs) are excluded. For isolation of total RNA containing small RNAs (e.g., miRNA) from cultured cells, additional RNA isolation protocols are available and described in the RNeasy Plus Micro Handbook and as a separate Supplementary Protocol to the RNeasy Plus Mini Kit.
The RNeasy Plus 96 Kit is compatible with a wide range of cell lines, providing purification of high-quality RNA with Agilent RIN values of close to 10 (see figure " High-quality RNA"). Complete genomic DNA removal by the kit (see figure "Effective genomic DNA removal") enables specific transcript detection in highly sensitive applications, such as quantitative, real-time RT-PCR analysis of low-abundance targets. In addition, reliable RNA purification from 102 to 106 cells allows real-time RT-PCR quantification over a wide dynamic range (see figure " Reliable RNA purification").

Principle

The RNeasy Plus procedure integrates QIAGEN’s innovative technology for selective binding of double-stranded DNA with well-established RNeasy technology. Efficient purification of high-quality RNA is guaranteed, without the need for additional DNase digestion. The purified RNA is ready to use and is ideally suited for downstream applications that are sensitive to low amounts of DNA contamination, such as quantitative, real-time RT-PCR.

Cells and easy-to-lyse tissues are first lysed and homogenized in highly denaturing guanidine-isothiocyanate–containing Buffer RLT Plus, which immediately inactivates RNases to ensure isolation of intact RNA. The lysate is then passed through a gDNA Eliminator spin column or gDNA Eliminator 96 plate that, in combination with the high-salt buffer, selectively and efficiently removes genomic DNA. Ethanol is added to provide appropriate binding conditions for RNA, and the sample is applied to an RNeasy spin column or 96-well plate. These specialized columns and 96-well plates contain a silica membrane that specifically binds RNA from lysed cells.
For fatty and difficult-to-lyse tissues, RNeasy Plus Universal Kits are recommended. For isolation of total RNA including miRNA from other sample types, we recommend miRNeasy Kits.

Procedure

The RNeasy Plus Micro Kit purifies total RNA from up to 5 x 105 cells or 5 mg tissue, and the RNeasy Plus Mini Kit isolates total RNA from up to107 cells or 30 mg tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 25 minutes (see flowchart  RNeasy Plus procedure). Samples are first lysed and homogenized. The lysate is passed through a gDNA Eliminator spin column, ethanol is added to the flow-through, and the sample is applied to an RNeasy spin column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 14 µl water using the RNeasy Plus Micro Kit or 30 µl water using the RNeasy Plus Mini Kit.

Different protocols are available for different starting materials. The protocols differ mainly in the lysis and homogenization of the sample. Once the sample is applied to the gDNA Eliminator spin column, the protocols are similar. The procedure provides an enrichment for mRNA since most RNAs <200 nucleotides (such as rRNAs and tRNAs) are excluded.

When disrupting and homogenizing tissues in Buffer RLT Plus (supplied with the RNeasy Plus Mini Kit), excessive foaming may occur. This foaming is substantially reduced by adding Reagent DX (supplied separately) to Buffer RLT Plus before starting disruption and homogenization. Reagent DX has been carefully tested with the kit, and has no effect on RNA purity or on downstream applications.
High-throughput RNA purification is achieved through the use of RNeasy 96 plates. Prior to application to the RNeasy 96 plate, cell lysates are first passed through a gDNA Eliminator 96 plate, (see figure " RNeasy Plus 96 procedure"). The gDNA Eliminator 96 plates are conveniently processed using a centrifuge (Centrifuge 4-16). RNA purification using RNeasy 96 plates is manual, and comprises 3 simple steps: bind, wash, and elute. The plates are rapidly and conveniently processed using either a centrifuge (Centrifuge 4-16 and Plate Rotor 2 x 96) or a combination of vacuum (QIAvac 96) and centrifuge. Up to 2 x 106 cells can be used as starting material when processing plates using a centrifuge, while up to 1 x 106 cells can be used when processing plates using a vacuum and centrifuge. The procedure provides an enrichment for mRNA since most RNAs <200 nucleotides (such as rRNAs and tRNAs) are excluded. The RNeasy Plus procedure can be modified to allow the purification of total RNA containing small RNAs, such as miRNA, from cultured cells.
