제품 세부 정보

DNeasy Blood & Tissue Kits provide fast and easy silica-based DNA purification in convenient spin-column and 96-well-plate formats. Most samples can be directly lysed with proteinase K, eliminating the need for mechanical disruption and reducing hands-on time. Optimized protocols for specific sample types provide reproducible purification of high-quality DNA for life science, genotyping, and veterinary pathogen research applications. Purification of DNA using the DNeasy Blood & Tissue Kit can be automated on the QIAcube.

성능

The efficient DNeasy Blood & Tissue procedure enables high yields of total DNA from animal blood and tissue samples (see table "Typical DNA yields from animal tissues using DNeasy Blood & Tissue Kits" and figure "DNA yields"). Optimized protocols ensure high yields from nonstandard samples, such as animal hair (see figure " Genotyping of horses"), as well as cultured cells, fixed tissues, or Gram-positive and -negative bacteria. Specialized online protocols are available for DNA purification from yeast, insects, hair, and other sample types.

DNeasy Blood & Tissue Kits simplify purification of DNA from a wide range of sample types, including animal species commonly encountered in life science, veterinary, and genotyping applications (see figure " High-quality DNA"). Purified DNA is free from PCR inhibitors, enabling sensitive detection in standard, multiplex (see figure " Efficient 16plex PCR"), and real-time PCR (see figure " Real-time PCR"). DNeasy Blood & Tissue Kits provide reliable results — from laboratory analysis of transgenic mice (see figure "High-throughput purification") to livestock breeding programs (see figure " Genotyping of pigs") and pedigree genotyping. Routine testing applications can be easily scaled up using the DNeasy 96 Blood & Tissue Kit (see figure "High-throughput purification").

원리

DNeasy Blood & Tissue Kits are designed for rapid purification of total DNA (e.g., genomic, mitochondrial, and pathogen) from a variety of sample sources including fresh or frozen animal tissues and cells, blood, or bacteria.

The DNeasy membrane combines the binding properties of a silica-based membrane with simple microspin technology or with the QIAGEN 96-Well-Plate Centrifugation System. DNA adsorbs to the DNeasy membrane in the presence of high concentrations of chaotropic salt, which remove water from hydrated molecules in solution. Buffer conditions in DNeasy Blood & Tissue procedures are designed to enable specific adsorption of DNA to the silica membrane and optimal removal of contaminants and enzyme inhibitors.

Purification requires no phenol or chloroform extraction or alcohol precipitation, and involves minimal handling. This makes DNeasy Blood & Tissue Kits highly suited for simultaneous processing of multiple samples. For higher-throughput applications, the DNeasy 96 Blood & Tissue Kit enables simultaneous processing of 96 or 192 samples.

절차

Reliable silica-membrane technology, in convenient spin-column or 96-well formats, ensures fast and reproducible DNA purification, eliminating the need for organic extraction and alcohol precipitation (see flowchart " DNeasy Mini and 96 procedures"). Samples are first lysed using proteinase K. Buffering conditions are adjusted to provide optimal DNA-binding conditions and the lysate is loaded onto the DNeasy Mini spin column or the DNeasy 96 plate. During centrifugation, DNA is selectively bound to the DNeasy membrane as contaminants pass through. Remaining contaminants and enzyme inhibitors are removed in two efficient wash steps and DNA is then eluted in water or buffer, ready for use.

DNeasy Mini spin columns are prepackaged in collection tubes and individually sealed, providing convenience and safety. The purification procedure using DNeasy Mini spin columns can be automated on the QIAcube. The DNeasy 96 Blood & Tissue Kit provides high-throughput processing in a 96-well format using the QIAGEN 96-Well-Plate Centrifugation System.

For plant-based foods, such as soy, tofu, and cookies, DNA isolation has been successfully carried out using the DNeasy Plant Mini Kit. The QIAamp DNA Stool Mini Kit has been used for isolation of genomic DNA from highly processed foods, and foods that contain high levels of PCR inhibitors, such as chocolate. For meat and processed meats, such as sausage, we suggest the DNeasy Blood & Tissue Kit.

See also the QIAGEN News article "Detection of genetically modified soybean and maize in raw and processed foodstuffs", and the accompanying editorial "Detecting genetically modified organisms in food."

FAQ ID -371

For DNA isolation using the QIAamp DNA Mini, or the DNeasy Blood & Tissue Kit, we recommend using carrier DNA when expected yields are below 10 ng. If possible, carrier DNAs such as poly-dA, poly-dT or poly-dA:dT should be used. Other carrier DNAs such as herring sperm DNA may interfere with subsequent PCR by binding primers nonspecifically.

Please note that poly-dA may interfere with oligo-dT primers, and, in this case, a different carrier DNA should be used. The concentration of carrier DNA should be at least 10 µg/ml. Optimal amounts need to be determined empirically for each application. The size distribution of carrier DNAs is typically in the range of 100 bp to 10 kb.

After proteinase K digestion, tissue samples can be stored in Buffer ATL for up 6 months at ambient temperature without any reduction in DNA quality.

FAQ ID - 3362

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 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.

FAQ ID -1254

Alcohol precipitation is commonly used for concentrating, desalting, and recovering nucleic acids. Since less alcohol is required for isopropanol precipitation, this is the preferred method for precipitation of DNA from large volumes. In addition, isopropanol precipitation can be performed at room temperature, which minimizes co-precipitation of salt that interferes with downstream applications.

Procedure

Adjust the salt concentration, for example, with sodium acetate (0.3 M, pH 5.2, final concentration) or ammonium acetate (2.0–2.5 M, final concentration).
Add 0.6–0.7 volumes of room-temperature isopropanol to the DNA solution and mix well.
Centrifuge the sample immediately at 10,000–15,000 x g for 15–30 min at 4°C
Carefully decant the supernatant without disturbing the pellet.
Wash the DNA pellet by adding 1–10 ml (depending on the size of the preparation) of room-temperature 70% ethanol. This removes co-precipitated salt and replaces the isopropanol with the more volatile ethanol, making the DNA easier to redissolve.
Centrifuge at 10,000–15,000 x g for 5–15 min at 4°C.
Carefully decant the supernatant without disturbing the pellet.
Air-dry the pellet for 5–20 min (depending on the size of the pellet).
Redissolve the DNA in a suitable buffer.

Tip: Use a buffer with a pH of 7.5–8.0, as DNA does not dissolve easily in acidic buffers. Often distilled water can have an acidic pH. The addition of EDTA protects the DNA from DNase digestion.

Tip: High-molecular-weight DNA, such as genomic DNA, should be redissolved very gently to avoid shearing. If the DNA pellet does not dissolve easily, heat at 55°C for 1–2 h with gentle shaking.

FAQ ID -2953

Yes, we have the following protocols:

Isolation of genomic DNA from mosquitoes or other insects using the QIAGEN Genomic tip (QG06).
Purification of total DNA from insects using the DNeasy Blood & Tissue Kit (DY14).

FAQ ID -904

Efficient DNA isolation requires thorough sample disruption and digestion.

Although the QIAamp and DNeasy procedures requires no mechanical disruption of the tissue sample, the lysis time will be reduced if the sample is ground in liquid nitrogen or mechanically homogenized in advance. For mechanical homogenization, a rotor–stator homogenizer, such as the QIAGEN TissueRuptor, or a bead mill, such as the QIAGEN TissueLyser, can be used.

To improve digestion of tough tissue samples, Proteinase K incubation at 56°C can be performed overnight. DNA yields may be improved by increasing the amount of Proteinase K or by adding additional proteinase K after several hours of digestion.

FAQ ID -374

We do not recommend using a vacuum manifold for DNA extraction with the DNeasy 96 Blood & Tissue Kit because:

Viscosity of the lysates varies from sample to sample. Therefore, the wells of the DNeasy 96 plate are at great risk of clogging.
Use of vacuum manifold would result in incomplete removal of ethanol and salts after washing with Buffer AW2. This will affect the purity and yield of samples.

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.

The 30 kb fragments are a good starting point for most of the library preparations. Furthermore, the purified DNA is free of protein, nucleases, and other contaminants and inhibitors, and therefore is suitable for NGS.

FAQ ID - 3517

We recommend using highly pure water for reconstitution. Ultrapure water (such as the one from MilliQ system, also known as type 1 water) with a resistivity of 18.2 MΩ-cm at 25°C can be used. In case you do not have access to type 1 water, QIAGEN offers Nuclease-Free Water (5 L, cat. No. 129117); and Nuclease-Free Water (1000 mL, cat. No. 129115). It is important that you do not use tap water as this may interfere with the extraction of the target analyte.

FAQ ID - 3986

The new Waste Tube is made from recycled plastic recovered from post-consumer plastic waste. Due to the slight composition differences of the raw material, the color of the tubes may differ from lot to lot. However, this has no effect on its intended use of collecting flow-through from sample binding and membrane washing. After each step, the flow-through is discarded, and the Waste Tube can be reused. The Waste Tube is only used to process waste and should never come into direct contact with the analyte of interest. For detailed instructions, you can watch our instructional video at www.qiagen.com/qiawavewastetube

FAQ ID - 3987

No, we were able to prove experimentally that cross-contamination does not occur through the reuse of the Waste Tubes. The Waste Tubes are used to collect the flow-through from the lysis and washing steps, where the flow-through is discarded afterwards. If the flow-through is to be used for further processing, we recommend the use of a Collection Tube.

FAQ ID - 3988

The concept of QIAwave includes the reconstitution of functional buffers. We recommend the use of glass bottles for this procedure. Glass bottles are easier to clean, sterilize and reuse than plastic bottles, further reducing the plastic footprint of the kit. If you do not have the option of using clean glass or plastic bottles, we recommend using our legacy kits.

FAQ ID - 3989

No, the chemistry between the QIAwave kits and the legacy kits is the same, and so is the performance. The QIAwave buffers come as concentrates, reducing the amount of plastic per bottle while maintaining the same functionality after reconstitution. The advantage of the QIAwave kits is the reduction of materials used for the kits, such as plastics, cardboard and paper. In addition, the QIAwave kits contain Waste Tubes made from 100% post-consumer plastic.
