Product Details

Die QIAprep 96 Turbo Kits enthalten QIAprep 96 und TurboFilter 96 Platten für die Aufreinigung von bis zu 20 µg molekularbiologischer Plasmid-DNA pro Vertiefung.
Für optimale Ergebnisse wird empfohlen, dieses Produkt zusammen mit QIAvac 96 zu verwenden.

Performance

Die QIAprep 96 Turbo Kits sind für die Isolierung von bis zu 20 µg reiner Plasmid- oder Cosmid-DNA zur Verwendung in molekularbiologischen Routineanwendungen wie Sequenzierung und Klonierung konzipiert (siehe Abbildung „Hochwertige DNA zur automatisierten Sequenzierung“).

Neben der Plasmidaufreinigung aus Escherichia coli können die QIAprep 96 Turbo Kits auch zur Aufreinigung von Plasmid-DNA aus Saccharomyces cerevisiae, Bacillus subtilis und Agrobacterium tumefaciens genutzt werden. Hinsichtlich der Protokolle für diese Anwendungen wenden Sie sich bitte an den Technischen Service von QIAGEN oder Ihren Händler vor Ort.

Principle

QIAprep 96 Platten (siehe Abbildung „QIAvac 96 mit 96-Well-Platte“) enthalten eine einzigartige Silika-Membran, die bis zu 20 µg DNA bei Vorliegen hochkonzentrierter chaotroper Salze bindet und die Elution in einem geringen Volumen eines salzarmen Puffers ermöglicht. Mit der QIAprep Membrantechnologie entfallen die zeitaufwändige Phenol-Chloroform–Extraktion und Alkoholausfällung sowie die Probleme und Nachteile, die mit losen Harzen und Aufschlämmungen einhergehen. Reine aus den QIAprep 96 Platten eluierte Plasmid-DNA ist sofort einsatzbereit, d. h. sie muss nicht ausgefällt, konzentriert oder entsalzt werden.

TurboFilter 96 Platten wurden speziell für die schnelle Bereinigung von Bakterienlysaten entwickelt, die unter hochkonzentrierten chaotropen Salzen gewonnen wurden. Bakterielle Rohlysate werden durch die TurboFilter 96 Platte vakuumfiltriert, so dass keine Zentrifugation benötigt wird. Partikelfreie Lysate fließen direkt in die Vertiefungen der QIAprep 96 Platte und können dort aufgereinigt und eluiert werden. Die TurboFilter-Technologie vereinfacht die QIAprep Plasmidaufreinigung und ermöglicht die vollständige Automatisierung des Verfahrens auf dem BioRobot 3000, BioRobot 8000 bzw. BioRobot Universal System.

Procedure

Die Plasmidaufreinigung mit den QIAprep 96 Turbo Kits erfolgt nach einem einfachen Verfahren zum Binden, Waschen und Eluieren (siehe Flussdiagramm „Das QIAprep-Verfahren“). Zunächst werden die Bakterienkulturen lysiert und die Lysate durch Filtration mit TurboFilter-Modulen bereinigt. Die so bereinigten Lysate werden dann auf die QIAprep 96 Platte aufgebracht, wo die Plasmid-DNA an der Silikamembran adsorbiert wird. Verunreinigungen werden weggewaschen und die reine DNA wird in einem kleinen Volumen Elutionspuffer oder Wasser eluiert.

Das QIAprep 96 Turbo Verfahren wird vollständig im 96-Well-Format durchgeführt, was die Probenhandhabung auf ein Minimum reduziert und die Bearbeitung von 96 parallelen Minipräps in 45–70 Minuten ermöglicht. Bakterienkulturen können in den zum Kit-Lieferumfang gehörenden 96-Well-Blöcken vermehrt und lysiert werden. Der QIAvac 96 Verteiler ist für die Inline-Filtration im 96-Well-Format konzipiert, so dass bereinigte Lysate aus der TurboFilter 96-Platte direkt in die Vertiefungen der QIAprep 96-Platte fließen, was einen hohen Durchsatz von 96 Proben im Parallelbetrieb ermöglicht. Das QIAprep 96 Turbo BioRobot Kit ist ein spezielles, für den BioRobot 8000 (nicht mehr erhältlich) oder das BioRobot Universal System optimiertes Kit-Format. Das Kit enthält alle für die automatische Herstellung von 96 hochreinen Plasmid-Minipräps erforderlichen Bestandteile.

FAQ

What is the advantage of running an analytical gel with fractions of my plasmid preparation?

Running fractions saved from each step in the plasmid preparation procedure on an agarose gel enables monitoring the performance of each crucial step in the protocol. If the plasmid DNA is of low yield or quality, the samples can be analyzed to determine at what stage of the purification procedure the difficulty occurred.

Aliquots can be taken from the cleared lysate and the flow-throughs as indicated in the relevant protocols, precipitated with isopropanol and resuspended in a small volume of TE buffer.

Please see the Troubleshooting Section of the QIAprep Miniprep Handbook and Appendix A of the QIAGEN Plasmid Purification Handbook for instructions, and a picture and legend explaining the typical results you may see. You can also access this information on our Plasmid Resource Pages.

FAQ ID -769
How do I know if my plasmid is a high- or low copy number type?

Find out which origin of replication your plasmid contains, and look at the table below for classification into high-copy or low-copy types. This table can also be found online at the QIAGEN Plasmid Resource Center in the section 'Growth of bacterial cultures; Plasmid Copy Number' . A way to determine experimentally if the copy number of your plasmid is high or low is to perform a miniprep. A high-copy plasmid should yield between 3-5 ug DNA per 1 ml LB culture, while a low-copy plasmid will yield between 0.2-1 ug DNA per ml of LB culture.

 

Origins of replication and copy numbers of various plasmids and cosmids

DNA construct Origin of Replication Copy number Classification
Plasmids      
pUC vectors pMB1* 500–700 high copy
pBluescript® vectors ColE1 300–500 high copy
pGEM® vectors pMB1* 300–400 high copy
pTZ vectors pMB1* >1000 high copy
pBR322 and derivatives pMB1* 15–20 low copy
pACYC and derivatives p15A 10–12 low copy
pSC101 and derivatives pSC101 ~5 very low copy
Cosmids      
SuperCos pMB1* 10-20 low copy
pWE15 ColE1 10-20 low copy

* The pMB1 origin of replication is closely related to that of ColE1 and falls in the same incompatibility group. The high-copy plasmids listed here contain mutated versions of this origin.

FAQ ID -350
Can I eliminate RNase A from buffer P1 for my plasmid preparation to obtain RNase-free DNA for in-vitro transcription?
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
I left Buffer P1 at room temperature after addition of RNase A, what shall I do?

Buffer P1 with RNase A used in QIAGEN Plasmid Purification Kits should be fine at room temperature for a few days. We would expect the enzyme to have some residual activity. However, optimal results cannot be guaranteed after storage at room temperature. If you notice that RNase A activity is substantially reduced, you can add fresh RNase A to your buffer.

We recommend that Buffer P1 with RNase A be stored in the refrigerator (2–8°C). RNase A will be stable for 6 months under this condition.

FAQ ID -859
What is the recommended culture medium for the QIAprep System?
Luria-Bertani (LB) broth is the recommended culture medium for use with QIAprep Kits, since richer broths such as TB (Terrific Broth) or 2x YT lead to extremely high cell densities, which can overload the purification system. Please review the section 'Culture Media' of Appendix A in the QIAprep Miniprep Handbook or visit our Plasmid Resource Center for additional information on optimal plasmid culturing and extraction conditions for all QIAGEN Plasmid Purification Kits.
FAQ ID -154
What is the composition of Buffer P2?

The composition of Buffer P2 is:

  • 200 mM NaOH
  • 1% SDS (w/v)

It should be stored at room temperature. Buffer P2 is the lysis 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 -203
What is the volume of the eluate when using either spin or vacuum procedures with the QIAprep 96 Turbo Miniprep Kit?

The average eluate volume when using either spin or vacuum protocols with the QIAprep 96 Turbo Miniprep Kit is 60 µl. Since 100 µl Buffer EB (10 mM Tris-Cl, pH 8.5) or water are added to each well for elution, the dead volume per sample is approximately 40 µl for both vacuum and spin procedures.

FAQ ID -1067
Can I use QIAprep Miniprep kits for low-copy plasmids and cosmids?

All QIAprep Miniprep Kits can be used for preparation of low-copy number plasmids and cosmids up to 50 kb. Below are recommendations for processing low-copy constructs using QIAprep technology:

  • Use up to 10 ml overnight E. coli cultures grown in LB medium
  • Be sure to include the optional Buffer PB wash step for all bacterial strains
  • When plasmids or cosmids are larger than 10 kb, pre-heat Buffer EB (or water) to 70°C prior to eluting DNA from the QIAprep membrane
  • When using 10 ml culture volume, it is recommended to double the volumes of Buffers P1, P2, and N3

See also QIAGEN News 1998, Issue 5 for an article entitled 'Isolation of a low-copy plasmid from agrobacterium using QIAprep technology'. Alternatively, the R.E.A.L. Prep 96 Plasmid Kit can be used for high-throughput purification of larger plasmids (e.g., BACs, PACs, and P1s). See QIAGEN News 1999, Issue 2 for an article entitled 'High-throughput purification of BACs with the new R.E.A.L. Prep 96 protocol'.

FAQ ID -127
Can I use LyseBlue with R.E.A.L. Prep 96, QIAwell Ultra, or QIAprep 96 Turbo Miniprep Kits for the BioRobot systems?

For high-throughput BioRobot plasmid isolation systems such as R.E.A.L. Prep 96, QIAwell Ultra, or QIAprep 96 Turbo Miniprep, there is no need for visual lysis control with LyseBlue reagent, because

  1. insufficient resuspension and lysis have not been observed with these systems
  2. automation systems already handle the lysis steps well enough
  3. optical reading capabilities are not implemented on our BioRobot platforms
FAQ ID -863
What are the additional plasmid bands I see on my gel?

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
What is the composition of Buffer PB?
Buffer PB contains a high concentration of guanidine hydrochloride and isopropanol. The exact composition of Buffer PB is confidential. However, this buffer can be purchased separately: Buffer PB.
FAQ ID -2791
Why is my plasmid DNA yield low?

Low yields of plasmid DNA can be caused by a number of different factors. The most common causes for low yield are poor culturing conditions and plasmid propagation, excessive amounts of starting material resulting in insufficient bacterial cell lysis and column overloading. When working with the anion-exchange based QIAGEN Plasmid Purification Kits, extra care is required during the isopropanol precipitation step, as the glassy DNA pellet may be difficult to see, and tends to be only loosely attached to the side of the tube.

We strongly recommend to review the information provided on our Plasmid Resource Page in the section 'Optimal results with QIAGEN plasmid kits', as it provides useful background information on growing bacterial cultures and general considerations for optimal results. It is also necessary to follow the instructions in the relevant protocols precisely to ensure the best plasmid yield and quality.

To determine at what stage of the procedure any problem occurred, save fractions from different steps of the purification procedure, and analyze by agarose gel electrophoresis. 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 the QIAGEN Plasmid Resource Center.

What is the RNase A concentration and composition of Buffer P1?

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
What is the recipe for SOC medium?

The components of the SOC medium are:

  • 0.5% Yeast Extract
  • 2% Tryptone
  • 10 mM NaCl
  • 2.5 mM KCl
  • 10 mM MgCl2
  • 10 mM MgSO4
  • 20 mM Glucose*

*Note: add Glucose after autoclaving the solution with the remaining ingredients, and letting it cool down. Sterilize the final solution by passing it through a 0.2 µm filter.

SOC medium can be stored at room temperature and is stable for several years.

FAQ ID -798
What is the white insoluble precipitate in my resuspended plasmid DNA pellet?

White insoluble material in the resuspended plasmid DNA pellet indicates carry-over of salts and/or carbohydrates. Ensure that isopropanol is used at room temperature for precipitation. Some bacterial strains, such as TG1 and JM100, naturally produce a high level of carbohydrates. However, carbohydrate contamination may also be observed when using other strains. The most common cause of this problem is over-growth of bacterial cultures. To avoid this, closely follow the guidelines for Plasmid DNA Preparation in the Handbook that was provided with the respective QIAGEN Plasmid Kit.

Useful hints and information on optimizing plasmid preparations can be found at the QIAGEN Plasmid Resource Center.

FAQ ID -352
Why would clumps occur following the addition of Buffer P2 when using LyseBlue Reagent in a plasmid preparation?

Clumps that occur after addition of Buffer P2 in a bacterial lysate containing LyseBlue reagent indicate poor resuspension of the bacterial cell pellet in Buffer P1. This handling error leads to inefficient cell lysis, and incomplete precipitation of SDS, cell debris, and genomic DNA. When resuspending the cell pellet, vortexing longer or resuspending the pellet by pipetting up and down can help.

If cells have been resuspended properly in P1, “brownish areas” after P2 addition just indicate poor mixing of P1 and P2. To overcome this, continue mixing the solution by inverting it gently until a homogeneous blue suspension is achieved.
