Product Details

QIAamp DNA Blood Kits provide silica-membrane-based DNA purification from whole blood, plasma, serum and other body fluids. The kits are designed for a range of sample
sizes from 200 μl up to 10 ml fresh or frozen human whole blood. QIAamp spin columns can be easily processed in a centrifuge or on vacuum manifolds. A convenient 96-well
format using centrifugation enables purification of DNA for labs that need high-throughput DNA purification from blood, buffy coat, plasma, serum, bone marrow, lymphocytes
and body fluids. A dedicated kit is also available for automated purification of 1–12 samples on the QIAcube Connect.

Performance

QIAamp DNA Blood Kits yield DNA sized from 200 bp to 50 kb, depending on the age and storage of samples . The purifiedDNA is suitable for long-range PCR amplification and

restriction fragment length polymorphism (RFLP) analysis used, for example, for paternity testing .

The QIAamp DNA Blood Midi Kit yields up to 94.5% recovery of DNA; the QIAamp DNA Blood Maxi Kit yields up to 95.8% recovery of DNA, depending on the starting cell densities。
  

Genomic DNA was purified from 2 ml (QIAamp Midi) or 10 ml (QIAamp Maxi) human whole blood and eluted in 300 µl (Midi) or 1 ml (Maxi) elution buffer. The first eluate was
loaded onto the column a second time and centrifuged again (i.e., re-eluted). Percentage DNA recovery was calculated by assuming that one leukocyte contains 6.6 pg DNA.

The QIAamp 96 DNA Blood Kit processes up to 200 µl sample size, with a preparation time of 192 samples in two to three hours, yielding highly pure DNA in less than one
minute per preparation. Even higher throughput can be achieved by staggering the procedure. QIAamp 96 plates provide well-to-well uniformity in DNA recovery and purity
(see figures "Sample reproducibility" and "Reproducibility of yield and purity"). The typical yield is 6 µg per 200 µl healthy whole blood, with an elution volume
of 50–200 µl.


The dedicated QIAamp DNA Blood Mini QIAcube Kit enables automated DNA isolation from blood and DNA isolation from body fluids on the QIAcube Connect. The kit includes
rotor adapters that are preloaded with QIAamp spin columns and elution tubes, delivering greater convenience and time savings (see figure "Significant time savings").
 Furthermore, ease of use is increased and user errors minimized. Waste is reduced, because the content of the dedicated kit is tailored for purification on the QIAcube
Connect and the superfluous tubes that are required for the manual procedure are not included.


If using the automatable QIAamp DNA Blood Mini Kit on the QIAcube Connect, the QIAamp DNA Blood Mini Accessory Set A and QIAamp DNA Blood Mini Accessory Set B provide
the convenience of extra buffers and reagents for automated sample prep.

Principle
No phenol–chloroform extraction is required. DNA binds specifically to the QIAamp silica-gel membrane while contaminants pass through. PCR inhibitors, such as divalent
cations and proteins, are completely removed in two efficient wash steps, leaving pure nucleic acid to be eluted in either water or a buffer provided with the kit. QIAamp
DNA Blood technology yields genomic, mitochondrial or viral DNA from blood and related body fluids ready to use in PCR and blotting procedures. QIAamp sample preparation
technology is fully licensed.

Procedure
QIAamp DNA Blood Kits simplify DNA purification from blood and DNA purification from body fluids with fast spin-column, vacuum, centrifugation or automated procedures
(see figure “QIAamp Spin Column procedure”). Fresh and frozen whole blood with common anticoagulants, such as citrate, EDTA and heparin, may be processed. If
processing QIAamp Midi or Maxi spin columns on vacuum manifolds additional Buffer AW1 [cat. no. 19081] and Buffer AW2 [cat. no. 19072] are required for use with the
 vacuum manifolds.

Vacuum processing with the QIAamp DNA Blood Mini Kit
With the QIAamp DNA Blood Mini Kit, blood can be processed by vacuum instead of centrifugation, for greater speed and convenience in DNA purification. QIAamp mini spin
 columns are accommodated on the QIAvac 24 manifold using VacValves and VacConnectors. VacValves should be used if sample flow rates differ significantly, to ensure
consistent vacuum. Disposable VacConnectors are used to avoid any cross-contamination. Use of VacConnectors also allows these QIAamp spin procedures to be performed on
 QIAvac 6S with QIAvac Luer Adapters.

Automated processing on the QIAcube Connect

The award-winning QIAcube Connect uses advanced technology to process QIAGEN spin columns, enabling seamless integration of automated, low-throughput sample prep into
laboratory workflows. All steps in the purification procedure are fully automated – up to 12 samples can be processed per run. The QIAcube Connect used together with
the dedicated QIAamp DNA Mini QIAcube Kit provides a winning combination for fast, easy and convenient DNA purification.

High-throughput processing in 96-well format

The QIAamp 96 spin procedure requires the QIAGEN 96-Well-Plate Centrifugation System’s deep rotor buckets to accommodate QIAamp 96 plates stacked on 96-well blocks.
Fresh or frozen whole blood treated with common anticoagulants such as, EDTA, citrate and heparin, may be used. Dried whole blood may be processed with additional
equipment and the use of a special protocol available from QIAGEN Technical Services or your local distributor.
