Product Details

QIAamp RNA Blood Mini Kitは、クエン酸、ヘパリン、EDTAのような一般的な抗凝固剤で処理した新鮮なヒト全血(最高1.5 ml)からシリカメンブレンをベースにした精製法で細胞RNAを分離します。QIAshredder Spin Columnを用いたホモジナイゼーション後、迅速なスピンカラム法によりRNAを簡単に精製します。精製はQIAcube上で完全自動化が可能です。


QIAamp調製法は、完全にRNase、夾雑物および酵素阻害物質を除去するので、全てのダウンストリームアプリケーションに最適な高品質RNAが得られます(図 " ノーザンブロット解析用の高品質RNA " および " RT-PCR解析")。

QIAamp RNA Blood Mini Kit を用いれば、DNA のコンタミを最小限に抑えた最高品質のRNAが調製できます。しかしどのようなRNA 精製法を用いても、わずかなDNA コンタミは避けられません。DNA に非常に高感度なRNAアプリケーションの場合には、残存するDNAの完全な除去が必要となります。このような場合には、QIAamp RNA調製中に簡便なカラム上で、サンプルのDNase 処理が行なえるQIAGEN RNase-Free DNase Set のご使用をお薦めします。

QIAamp RNA Blood Mini Kit を使用すれば、シリカメンブレンテクノロジーによって細胞RNAを精製することができます。フェノール/クロロホルム抽出は不要です。RNAは選択的にQIAampシリカゲルメンブレンに結合し、夾雑物は洗い流されます。2価の陽イオンおよびタンパク質などのPCR阻害物質は2回の効率的な洗浄ステップにより完全に除去され、残った高純度のRNAが水あるいはキットに添付のバッファーで溶出されます。



QIAamp RNA Blood Mini Kit は迅速なスピンカラム法により、血液からのRNA精製を容易にします(図 " QIAamp RNA Blood Mini 操作手順")。赤血球を選択的に溶解し、白血球を遠心操作で収集します。その後、RNaseを急速に不活化する高度な変性の条件を使用して、白血球を溶解します。QIAshredder Spin Columnによるホモジナイゼーションの後、サンプルをQIAamp Spin Column にアプライします。トータルRNAがQIAampメンブレンに結合し、夾雑物が洗浄除去され、高純度なRNA が、30~100 µlのRNaseフリーの水(本キットに添付)で溶出されて、全てのダウンストリームアプリケーションで即使用可能となります。

FAQ ID -2951
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 difference between QIAGEN Protease and QIAGEN Proteinase K provided in various QIAamp Kits?

QIAGEN Proteinase K is a subtilisin-type protease, which cleaves at the carboxyl side of hydrophobic, aliphatic and aromatic amino acids. It is particularly suitable for short digestion times. It possesses a high specific activity over a wide range of temperatures and pH values with substantially increased activity at higher temperature. Soluble calcium is not essential for enzymatic activity. This means that EDTA, which is used to inhibit Mg2+-dependent enzymes such as nucleases, will not inhibit Proteinase K activity.

QIAGEN Protease is a broad-specificity Serine protease with high activity, cleaving preferentially at neutral and acidic residues. It is an economical alternative to Proteinase K for isolation of native DNA and RNA from a variety of samples.

FAQ ID -761
Can I clean up my DNase treated RNA samples using RNeasy columns?
Yes. The RNeasy MinElute Cleanup Kit has been developed specifically for cleaning up and concentrating RNA samples. You can also follow the protocols for RNA cleanup in the RNeasy Mini and RNeasy Midi/Maxi Handbook.
FAQ ID -286
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
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
What is the average amount of DNA and RNA present in 1 ml normal serum?

According to an Interview with Professor Dennis Lo published in QIAGEN News Molecular Diagnostics, Issue No. 5, 2002, healthy individuals have about 500-1000 genome equivalents (DNA) per ml serum/plasma.

For free-circulating DNA in plasma, the concentration can range from 1–100 ng/ml in healthy individuals.

FAQ ID -635
What has to be done to an RNA sample before loading it onto an Agilent Bioanalyzer?

For RNA isolated on the BioRobot EZ1 and BioRobot M48:

The RNA can be directly applied to the Agilent Bioanalyzer, since it is being denatured in the final protocol steps of these isolation procedures.

For RNA prepared with all other QIAGEN RNA Isolation Products:

We recommend to denature the samples in a water bath for 2 min at 70°C, and then place them directly on ice prior to loading them onto the Agilent Bioanalyzer.


FAQ ID -528
Why does my isolated RNA have a low OD 260/280 ratio?

The A260/ A280 ratio is influenced considerably by pH. Since water is not buffered, the pH and the resulting A260/A280 ratio can vary greatly. Lower pH results in a lower A260/ A280 ratio and a reduced sensitivity to protein contamination*.

For accurate values, we recommend measuring absorbance in 10 mM Tris·Cl, pH 7.5. Always be sure to calibrate the spectrophotometer with the same solution. Please see the Appendix sections in the RNeasy handbooks for additional information.

FAQ ID -97
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
How should I quantify RNA isolated with RNeasy Kits?

The concentration of RNA isolated with RNeasy Kits can be determined by measuring the absorbance at 260 nm (A260) in a spectrophotometer. Absorbance readings should be greater than 0.15 to ensure significance. An absorbance of 1 unit at 260 nm corresponds to 40 µg of RNA per ml (A260 = 1 = 40 µg/ml). This relationship is valid for measurements in water. Therefore, dilute RNA in water to quantify it spectrophotometrically.

An example of the calculations involved in RNA quantification is shown below. Use the buffer in which the RNA is diluted to zero the spectrophotometer:

  • Volume of RNA sample = 100 µl
  • Dilution = 10 µl of RNA sample + 490 µl distilled water (1/50 dilution)
  • Absorbance of diluted sample measured in a 1 ml cuvette (RNase-free): A260 = 0.23
  • Concentration of original RNA sample = 40 x A260 x dilution factor = 40 x 0.23 x 50
  • RNA concentration: 460 µg/ml

  • Total yield = concentration x volume of sample (ml) = 460 µg/ml x 0.1 ml
  • RNA yield: 46 µg

For additional information on RNA quantitation and handling, see the Appendix section in the RNeasy Mini Handbook.
