製品詳細

HiSpeed Plasmid Kits は超高速、ラージスケールでの陰イオン交換ベースのプラスミド調製を行ない、遠心操作は必要ありません。精製したDNAは、CsCl 密度勾配遠心法を2 回行なって得られる精製グレードに匹敵し、トランスフェクション等のアプリケーションに最適です。

パフォーマンス

HiSpeed Plasmid Kits は、真空マニホールドなしでの高速の大量プラスミド調製用にQIAfilter Cartridge、HiSpeed TipおよびQIAprecipitatorモジュールを備えています。シリンジフォーマットのQIAfilterとQIAprecipitatorモジュールにより従来の陰イオン交換調製法における遠心操作の必要がなくなり、プラスミド精製がより迅速で簡単になりました。150～250 ml の培養液から最高750 µg（Maxi）、または50～150 ml の培養液から最高200 µg（Midi）の高コピープラスミドDNAを精製することができます（培養液の容量はプラスミドコピー数、挿入DNAのサイズ、宿主株、培養液に依存）。HiSpeed Tip は、流速が早くなり、プラスミド精製のためのDNA結合、洗浄および溶出ステップがより迅速に行なえます。

HiSpeed Tipsの画期的な陰イオン交換樹脂は核酸精製用に特化して開発されています。本製品の優れた核酸分離能力により、CsCl 密度勾配遠心分離法を2回行なって得たDNAの純度に匹敵、あるいはそれ以上の純度のDNAが調製されます。

原理

QIAfilter Cartridges（図" QIAfilter Cartridge"）は、バクテリア細胞のアルカリ溶解後に行なう遠心操作による清澄化に代わる方法として開発された特別なフィルターです。QIAfilter Cartridges はSDS沈殿物を完全に取り除くばかりではなく、遠心操作に必要な時間よりずっと早くバクテリアライセートを清澄化します。充填済みHiSpeed Tipsはオープンカラムで操作し、乾燥することはなく、プラスミド調製に必要なマニュアルでの作業時間を短縮できます。

ユニークな QIAprecipitatorモジュール（図" QIAprecipitatorモジュール"）により、イソプロパノールで沈殿させたDNAを収集するために従来の遠心操作の必要はなくなりました。沈殿したDNA は、QIAprecipitator モジュールで捕獲され、イソプロパノールやバッファーは流出します。このDNAはTEバッファーあるいは水によりQIAprecipitator からマイクロ遠心チューブに簡単に溶出されます。このモジュールにより、遠心操作後に上清を除去する際に起こり得るペレットを失うリスクもなくなりました。

裏付けデータと数値

QIAprecipitator module.

The unique QIAprecipitator module replaces the centrifugation step traditionally used to collect isopropanol-precipitated DNA following purification. The QIAprecipitator module traps the precipitated DNA while the isopropanol-buffer mixture flows through. The DNA is then simply eluted from the QIAprecipitator into a microcentrifuge tube with TE buffer or water. This unique module also eliminates the risk of pellet loss, which can occur during decanting of the supernatant following centrifugation.

FAQ ID -413

No, RNase A should not be omitted from buffer P1. It is required to prevent RNA contamination of the purified plasmid DNA. RNase A will not interfere with downstream in-vitro transcription experiments, since it will be efficiently removed during the plasmid purification procedures using QIAGEN Plasmid Kits.

FAQ ID -366

Yes, when eluting DNA from the QIAprecipitator Modules of the HiSpeed Plasmid Kits, water or buffers commonly used to dissolve DNA (e.g., Tris) may be employed.

Note: Store DNA at -20°C when eluted with water as DNA may degrade in the absence of buffering and chelating agents.

FAQ ID -306

Open circular plasmid, resulting from single strand nicks, usually migrates slower in agarose gels and forms (faint) bands above the supercoiled plasmid DNA band. Sometimes an additional band of denatured supercoiled DNA migrates just below the supercoiled form. This form may result from prolonged alkaline lysis with Buffer P2 and is resistant to restriction digestion.

For a detailed description on how to run and interpret an analytical gel, please see Appendix A in the QIAGEN Plasmid Purification Handbook: "Agarose Gel Analysis of the Purification Procedure", or visit this link.

FAQ ID -1059

Redissolve the DNA by warming the solution slightly, e.g. incubate it at 37°C, and allow more time for redissolving.

FAQ ID -572

No. Ethanol is not recommended when using the QIAprecipitator module of the HiSpeed Plasmid Kits for DNA precipitation. The finer precipitates formed with ethanol are likely to clog the QIAprecipitator.

FAQ ID -354

Use 500 µl instead of 1 ml of Buffer TE for elution of plasmid DNA from the QIAprecipitator of the HiSpeed Plasmid Kits. If low copy plasmids are used, the lysates of two QIAfilter Cartridges can be filtered into one equilibrated HiSpeed Tip. HiSpeed Maxi Kits will result in higher DNA concentration than HiSpeed Midi Kits, because the QIAprecipitators in both kits (Midi- and Maxi Module) use the same elution volume.

FAQ ID -1061

When using the QIAprecipitator module of the HiSpeed Plasmid Midi- or Maxi Kits, make sure to dry the membrane by pressing air through the QIAprecipitator at least twice. Dry the outlet nozzle of the QIAprecipitator with absorbent paper. This will prevent carry-over of alcohol into the eluate and enable optimal performance of the extracted DNA downstream.

Do not load eluate from from several columns on the QIAprecipitator, and be sure that the correct precipitator size is used for the corresponding HiSpeed Tip. Do not replace the isopropanol with ethanol for precipitation, since the use of ethanol will lead to a finer precipitate that can clog the module.

To prevent breakage and leakage of the module it is important to avoid excessive force, bending, or twisting while attaching the QIAprecipitator to the syringe. Do not stress the inlet by resting one edge of the QIAprecipitator on a hard surface (e.g., the edge of a sink) and depressing the syringe plunger. Always apply gentle, even, pressure perpendicularly to the QIAprecipitator.

FAQ ID -144

When using the silica-based QIAprep Spin Miniprep Kit, a protocol is contained in the QIAprep Miniprep Handbook, in Appendix C: Special Applications. The protocol is called: 'Purification of plasmid DNA prepared by other methods'.

For our anion-exchange based Plasmid Purification Kits, a protocol can be accessed online at our Plasmid Resource Center, and is called 'Re-Purification of Plasmid DNA Prepared by Methods other than QIAGEN Tips'.

FAQ ID -1031

The composition of Buffer TE is:

10 mM Tris·Cl, pH 8.0
1 mM EDTA

Buffer TE is a commonly used DNA resuspension and storage buffer. It is supplied in QIAGEN's Endofree Plasmid Kits, and used for plasmid DNA resuspension in combination with other QIAGEN Plasmid Kits. Details on buffer preparation and storage are presented in Appendix B of the QIAGEN Plasmid Purification Handbook.

FAQ ID -416

The lowest elution volume that should be used for both the QIAprecipitator Midi and the Maxi Module provided in the HiSpeed Plasmid Kits is 500 ul. The official elution volume for both modules is 1 ml. If a higher DNA concentration is desired and a reduction in yield of up to 10% is acceptable, the elution volume can be reduced. Elution volumes smaller than 500 ul will lead to incomplete wetting of the QIAprecipitator membrane and further reduced DNA yields.

FAQ ID -307

A precipitate forming upon adding LyseBlue reagent to Buffer P1 is a normal observation. This precipitate will completely dissolve after addition of Buffer P2. Please be sure to shake Buffer P1 vigorously before use to completely resuspend LyseBlue particles.

FAQ ID -1045

No, the QIAprecipitator Midi and Maxi modules of the HiSpeed Plasmid Midi- and Maxi Kits are not interchangeable. Each module has been designed for different capacities and recoveries.

FAQ ID -308

The composition of Buffer P1 is:

50 mM Tris·Cl, pH 8.0
10 mM EDTA
100 µg/ml RNase A

After RNase A addition, the buffer should be stored at 2–8°C.

Buffer P1 is the resuspension buffer used in a variety of QIAGEN kits for plasmid DNA purification. Details on buffer preparation and storage are presented in Appendix B of the QIAGEN Plasmid Purification Handbook.

FAQ ID -198

No. Although both Buffers N3 of the QIAprep Spin Miniprep and P3 of the QIAGEN Plasmid Kits perform the neutralization step in an alkaline lysis procedure, they are completely different. Buffer N3 contains a proprietary formula that sets up binding conditions for the QIAprep Miniprep column's silica-gel-membrane. Buffer P3 sets up binding conditions for QIAGEN anion-exchange columns. Our website explains QIAGEN's nucleic acid purification technologies in more detail.

FAQ ID -310

The composition of Buffer P3 is:

3.0 M potassium acetate, pH 5.5

Buffer P3 is the neutralization buffer used in QIAGEN's anion-exchange based Kits for plasmid preparation. Details of buffer preparation and storage are presented in Appendix B of the QIAGEN Plasmid Purification Handbook.

FAQ ID -418

Buffer QC is the wash buffer used in QIAGEN Plasmid Kits for plasmid purification and in QIAGEN Blood & Cell Culture kits.

The composition of Buffer QC is:

1.0 M NaCl
50 mM MOPS, pH 7.0
15% isopropanol (v/v)

To make 1 liter of solution, dissolve 58.44 g NaCl, 10.46 g MOPS (free acid) in 800 ml distilled water. Adjust the pH to 7.0 with NaOH. Add 150 ml pure isopropanol. Adjust the volume to 1 liter with distilled water. Store at 15–25°C.

FAQ ID -412

It is important to completely mix and lyse bacterial cells with plasmid Buffers P1 and P2. Incomplete mixing results in sticky or slimy areas of lysate, which will clog the filter matrix. It is recommended to completely resuspend cells in Buffer P1 and vigorously mix after addition of Buffer P2. Also mixing after Buffer P3 addition needs to be complete to allow fluffy precipitation of cell debris, which will float up. If the white debris does not float, dislodge it from the QIAfilter barrel wall (e.g. using a sterile pipette tip). Otherwise it will collect on the filter matrix and can lead to clogging. Use of LyseBlue reagent will help to achieve proper mixing results.

FAQ ID -1060
