- Removal of contaminants and inhibitors
Cat. No. / ID: 965842
The QIAamp 96 DNA Swab BioRobot Kit provides automated DNA purification from up to 192 swabs on the BioRobot Universal System using proven QIAamp silica-membrane technology. Up to 192 samples are processed in less than 2.5 hours. The procedure is optimized for use with air-dried swabs with plastic shafts and cotton or DACRON tips, although other swab types can be used.
Proven QIAamp 96 technology provides well-to-well uniformity in DNA recovery and purity with no cross-contamination between samples (see figure " Cross-contamination test"). The effective removal of enzyme inhibitors ensures reliable performance in downstream applications such as TaqMan®, LightCycler, and iCycler analyses (see figure " Reliable performance").
DNA isolated with the QIAamp 96 DNA Swab BioRobot Kit is ready to use in a wide range of applications in molecular diagnostics and forensic science:
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 four efficient wash steps, leaving pure DNA to be eluted in either water or a buffer provided with the kit. QIAamp technology yields DNA from swabs ready to use in PCR and blotting procedures.
The QIAamp 96 DNA Swab BioRobot Kit simplifies isolation of DNA from swabs with a fast automated 96-well–plate procedure (see flowchart " QIAamp 96 DNA Swab BioRobot procedure"). The procedure is optimized for use with air-dried swabs with plastic shafts and cotton or DACRON tips, although other swab types can be used. The typical yield for the QIAamp 96 DNA Swab BioRobot Kit is 1–2 µg per swab (buccal swabs), with an elution volume of 150 µl.
QIAamp sample preparation technology is fully licensed.
The QIAamp 96 DNA Swab BioRobot Kit provides QIAamp technology in a convenient 96-well format for high-throughput purification needs. The DNA from up to 96 swab samples is purified in under 2 hours. Sample types include:
|yield||1–2 µg per swab|
|forautomatedprocessing||BioRobot Universal System, BioRobot Genotyping, BioRobot 9604|
|sampleamount||1 swab per well|
It is strongly advised to follow the recommendations for preparing sample material provided in the corresponding Protocol Sheet to ensure reliable results.
Plasma: It is recommended to perform plasma separation immediately after blood collection when using EDTA or citrate as anticoagulant to prevent the release of genomic DNA into the plasma fraction.
Urine: Because circulating cell-free DNA in non-stabilized urine samples is rapidly degraded after sample collection due to high nuclease activity, eluates may contain no DNA or exhibit low DNA concentration. Therefore, it is recommended to stabilize urine samples. Even when using stabilized urine, it is recommended to perform a centrifugation step immediately after stabilization to prevent the release of genomic DNA from cells. Alternatively, non-stabilized urine samples can be processed immediately after collection and centrifugation using ATL-pretreatment and automated DNA extraction as described in the corresponding Protocol Sheet.
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.

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.).
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.
