Product Details

The QIAwave RNA Mini Kit is an eco-friendlier version of our standard RNeasy Mini Kit. The QIAwave Kit uses 61% less plastic and 38% less cardboard than our standard kit and offers waste tubes made from 100% post-consumer recycled plastic that you can reuse throughout the procedure. QIAwave buffers also come as concentrates, reducing the amount of plastic by 86% per bottle. To save paper, there are no printed protocols in the kit. Instead, you can download the protocols you need from the resources list or by simply scanning the QR code inside the box lid. So, while the kit packaging and components of our QIAwave Kit may look different, it’s as easy to use as the RNeasy Mini Kit, and the chemistry and performance are identical.

In partnership with My Green Lab, we've also assessed the environmental impact of this kit. My Green Lab ACT (accountability, consistency, and transparency) environmental impact factor labels are designed to evaluate and score products on several sustainability criteria. These include:

  • manufacturing
  • responsible chemical management
  • sustainable content within products and packaging materials
  • disposal of the packaging at the end of life

Products are scored from 1 to 10 except for energy and water consumption, which are scored as 1 point per kWh or gallon, respectively. A low score means a lower environmental impact.

You can view the ACT labels for this kit in the Resources section below.

The QIAwave RNA Mini Kit offers you fast purification of high-quality RNA from cells, tissues, and yeast using silica-membrane RNeasy Mini Spin Columns. Before extraction, you can stabilize tissue samples using RNAprotect Tissue Reagent or Allprotect Tissue Reagent, and to efficiently homogenize your tissue samples, you can use the TissueRuptor II, TissueLyser II or LT system.
If you have too many samples to prep manually, you can automate your sample extraction on the QIAcube Connect.

Performance

The QIAwave RNA Mini Kit gives you highly reproducible yields of total RNA from animal or human cells, animal or human tissues, and yeast (see table “Total RNA yields obtained with RNeasy Mini Spin Columns” and figure " RT-PCR of RNA from as few as 100 cells").
The performance between our QIAwave RNA Mini Kit and RNeasy Mini Kit is identical because the chemistry is the same. We’ve also shown that both kits outperform competitors’ kits (see figure  "QIAwave RNA Mini Kit performance").

Principle

The QIAwave RNA Mini Kit allows you to efficiently purify total RNA from samples such as:

  • microdissected tissues and fine needle aspirates
  • milligram amounts of fibrous tissues, including heart and muscle tissue
  • small numbers of cells down to a single cell (e.g., FACS sorted cells)

For microdissected FFPE tissues, we recommend using the RNeasy FFPE Kit. The QIAwave Kit simplifies total RNA isolation by combining the stringency of guanidine-isothiocyanate lysis with the speed and purity of silica-membrane purification. The QIAwave RNA Mini Kit also gives you high-quality RNA with minimal copurification of DNA.

Procedure

With the QIAwave Kit, you can purify RNA in four simple steps (see flowchart " QIAwave RNA Mini Procedure").

  1. Lyse and homogenize samples (see table "Amount of starting material for the QIAwave RNA Mini Kit").
  2. Add ethanol to the lysate to provide ideal binding conditions.
  3. Load the lysate onto the RNeasy silica membrane. At this point, the RNA binds to the silica membrane and all contaminants are efficiently washed away. If your downstream applications are sensitive to very small amounts of DNA, you can remove any residual amounts of DNA using a convenient on-column DNase treatment.
  4. Pure, concentrated RNA is then eluted in water.

In addition to our standard protocol, we also provide a variety of special application protocols.
If you have too many samples to process manually, you can automate the purification process on the QIAcube Connect. The QIAcube Connect allows you fully automate the entire purification procedure for up to 12 samples per run.
QIAwave buffers come as concentrates that you can easily reconstitute by adding water and/or ethanol; please check the handbook for details. QIAwave RNeasy Mini Spin Columns and Waste Tubes come in individual bags and need to be preassembled before you start the protocol. This takes a little extra time, but it does reduce plastic waste.

FAQ

Do you have a protocol for purification of cytoplasmic RNA from animal cells?

Yes, please follow the Supplementary Protocol 'Purification of cytoplasmic RNA from animal cells using the RNeasy Mini Kit' (RY25).

 

 

FAQ ID -1257
How much RNA does a typical mammalian cell contain?

The RNA content and RNA make up of a cell depend very much on its developmental stage and the type of cell. To estimate the approximate yield of RNA that can be expected from your starting material, we usually calculate that a typical mammalian cell contains 10–30 pg total RNA.

The majority of RNA molecules are tRNAs and rRNAs. mRNA accounts for only 1–5% of the total cellular RNA although the actual amount depends on the cell type and physiological state. Approximately 360,000 mRNA molecules are present in a single mammalian cell, made up of approximately 12,000 different transcripts with a typical length of around 2 kb. Some mRNAs comprise 3% of the mRNA pool whereas others account for less than 0.1%. These rare or low-abundance mRNAs may have a copy number of only 5–15 molecules per cell.

FAQ ID -2946
What kits does QIAGEN offer to extract RNA from whole blood?

Several kit options are available for this application. We recommend using the PAXgene Blood RNA System, which enables the collection, stabilization and transportation of 2.5 ml human whole blood samples, and subsequent rapid and efficient isolation of cellular RNA.

Other products for the isolation of RNA from whole human blood are the QIAamp RNA Blood Mini Kit and the RNeasy Midi Kit for processing up to 1.5 ml and 10 ml human whole blood, respectively.

FAQ ID -304
What is the composition of Buffer RLT?

The exact composition of Buffer RLT is confidential. This buffer is a proprietary component of RNeasy Kits. Buffer RLT contains a high concentration of guanidine isothiocycanate, which supports the binding of RNA to the silica membrane. Buffer RLT can be purchased separately (cat. no. 79216)

Note: note that ß-mercaptoethanol should be added to Buffer RLT before use to effectively inactivate RNAses in the lysate (10 µl ß-Mercaptoethanol per 1 ml Buffer RLT).

FAQ ID -2793
What is the maximum binding capacity of RNeasy spin columns?
The maximum binding capacity of the RNeasy Mini spin columns is 100 ug RNA. It is 1 mg for RNeasy Midi columns and 6 mg for RNeasy Maxi columns. The maximum RNA binding capacity of the RNeasy MinElute spin columns is 45 µg.

Do you have a protocol for the isolation of RNA from leukocytes in milk?
Yes, please follow the User-Developed Protocol 'Isolation of RNA from leukocytes in milk using QIAGEN RNeasy Kits' (RY12).
FAQ ID -952
What is the key technical challenge in isolating high quality RNA from cell or tissue samples?

Ribonucleases are the principal threat to any RNA isolation procedure. In addition, copurification of inhibitory contaminants is a major problem when isolating RNA from certain tissue sources. To minimize the threat, gloves should be worn at all times, and special care must be taken to use RNase-free reagents and labware.

In addition, tissue/cell lysis steps are typically carried out with lysis buffers containing guanidine isothiocyanate, a potent protein denaturant. It is very important to use a sufficient amount of lysis buffer during RNA isolation. We recommend using at least 10x volume of lysis buffer to tissue/cell pellet.

In general, for fast purification of high-quality RNA we recommend QIAGEN’s RNeasy Kits. It is more challenging to isolate high-quality RNA from tissue samples than from cultured cells, especially those tissues containing high levels of RNase, or difficult-to-homogenize tissues. Examples of such tissues include liver, heart, skin, and conjunctive tissues. Many tissue samples also contain difficult-to-remove contaminants (such as polysaccharides, collagen, fats, lipids or fibrous components) that may interfere with subsequent enzymatic reactions if not removed from the RNA preparation. For purification of high-quality RNA from difficult tissues we recommend QIAGEN’s RNeasy Plus Universal Kit.

FAQ ID -2656
Can QIAquick Kits be used to clean up RNA samples?
Although it is possible to use the QIAquick Nucleotide Removal Kit and QIAquick PCR Purification Kit for RNA purification, the conditions are not optimized for RNA, nor are RNase-free conditions guaranteed. The RNeasy MinElute Cleanup Kit is recommended for clean-up, concentration and desalting of RNAs above 200 bases in length.
FAQ ID -490
Are RNeasy spin columns sold separately?
At this time, RNeasy spin columns are not sold separately.
FAQ ID -159
Can the RNase-Free DNase Set be used for DNase digestions of RNA in solution?

Yes. Even though buffer RDD in the RNase-Free DNase Set is optimized for on-column DNase digestion, the buffer is also well-suited for efficient DNase digestion in solution. Please note that the reaction must be cleaned up after the off-column DNase digest to remove the enzyme and buffer RDD, which will interfere with subsequent RT reactions.

A protocol for in-solution DNase digestion using the RNase-Free DNase Set can be found in Appendix C of the RNeasy MinElute Cleanup Handbook. For subsequent RNA Cleanup, use either the RNeasy MinElute Cleanup Kit, or follow the instructions for RNA Cleanup in the RNeasy Mini Handbook.

 

FAQ ID -619
Which kit should be used to extract RNA from adipose tissue, brain, and other fatty animal tissues?
The RNeasy Lipid Tissue Mini and Midi Kits are designed to extract RNA from up to 100mg and 500mg of fatty tissue, respectively.
FAQ ID -467
What can be used as an alternative to the A260 measurement for quantification of small amounts of RNA and DNA?

Small amounts of RNA and DNA may be difficult to measure spectrophotometrically. Fluorometric measurements, or quantitative RT-PCR and PCR are more sensitive and accurate methods to quantify low amounts of RNA or DNA.

Fluorometric measurements are carried out using nucleic acid binding dyes, such as RiboGreen® RNA Quantitation Reagent for RNA, and PicoGreen® DNA Quantitation Reagent for DNA (Molecular Probes, Inc.).

FAQ ID -728
How can I minimize degradation of RNA from my pancreas sample?

Pancreas is very high in RNases. Therefore, it is important to minimize the time between harvesting the tissue and snap freezing or stabilization in RNAprotect Tissue Reagent.  Use of 3-5% ß-mercaptoethanol in Buffer RLT instead of 1% may also improve the results.


FAQ ID -624
What are the effects of low A260/A230 ratios in RNA preparations on downstream applications?

The efficiency of downstream applications depends strongly on the purity of the RNA sample used.  Pure RNA should yield an A260/A230 ratio of around 2 or slightly above; however, there is no consensus on the acceptable lower limit of this ratio.  Possible candidates that can increase the A230 include “salt”, carbohydrates, peptides, and phenol (or aromatic compounds in general).  In our experience, the increased absorbance at 230 nm in RNA samples is almost always due to contamination with guanidine thiocyanate, present at very high concentrations in the lysis buffer or extraction reagent used in most RNA purification procedures.

Please find an article discussing the effect of low 260/230 ratios in RNA preparations on downstream applications on page 7 of QIAGEN Newsletter March 15, 2010 . In summary, we found that concentrations of guanidine thiocyanate of up to 100 mM in an RNA sample do not compromise the reliability of downstream applications.

 

 

FAQ ID -2248
How do I safely inactivate biohazardous flow-through material?

Always dispose of potentially biohazardous solutions according to your institution’s waste-disposal guidelines. Although the lysis and binding buffers in QIAamp, DNeasy, and RNeasy kits contain chaotropic agents that can inactivate some biohazardous material, local regulations dictate the proper way to dispose of biohazards. DO NOT add bleach or acidic solutions directly to the sample-preparation waste. Guanidine hydrochloride in the sample-preparation waste can form highly reactive compounds when combined with bleach.
Please access our Material Safety Data Sheets (MSDS) online for detailed information on the reagents for each respective kit.

FAQ ID -12
What is the composition of Buffer RW1?

The exact composition of Buffer RW1 is confidential. Buffer RW1 is a proprietary component of RNeasy Kits. Buffer RW1 contains a guanidine salt, as well as ethanol, and is used as a stringent washing buffer that efficiently removes biomolecules such as carbohydrates, proteins, fatty acids etc., that are non-specifically bound to the silica membrane. At the same time, RNA molecules larger than 200 bases remain bound to the column.

Note: Buffer RW1 should not be used for isolation of small RNAs, for example, microRNAs or fragmented RNA from formalin-fixed tissues, as these smaller fragments will be washed away.  Buffer RWT should be used instead.
