Product Details

DNeasy Blood & Tissue Kits quickly extract DNA using a silica-based, phenol- and chloroform-free process in spin-column and 96-well-plate formats. For most samples, direct lysis with proteinase K eliminates the need for mechanical disruption, reducing hands-on time. Tailored protocols for specific samples ensure consistent extraction of high-quality DNA, perfect for life science, genotyping, and veterinary pathogen research. Kits can be automated on QIAcube Connect.

For a more sustainable alternative, the QIAwave DNA Blood & Tissue Kit, reduces plastic and cardboard usage by up to 62% and 58%, respectively. The kit includes waste tubes made from 100% recycled plastic, which can be reused throughout the procedure. QIAwave buffers are concentrated, decreasing plastic use in each bottle by up to 90%. Despite visual differences, the QIAwave Kit remains as user-friendly as the standard kit, with identical chemistry and performance. Note: Sterile glass bottles are required for buffer reconstitution.

Performance

The efficient DNeasy and QIAwave DNA Blood & Tissue Kits procedure enables high yields of total DNA from animal blood and tissue samples (see table Typical DNA yields from animal tissues and figure DNA yields). Optimized protocols ensure high yields from nonstandard samples, such as animal hair (see 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.

Since the chemistry of the QIAwave DNA Blood & Tissue Kit and DNeasy Blood & Tissue Kits are identical, they exhibit identical performance. Both kits showed superior performance compared to competitor kits (see figure “ QIAwave DNA Blood & Tissue Kit performance”).

Following the standard protocol of the QIAwave DNA Blood & Tissue Kit, high yields of total DNA can be isolated from animal blood and tissue samples (see table -"Typical DNA yields from animal tissues using QIAwave DNA Blood & Tissue-" and figure " DNA yields"). Furthermore, optimized protocols to ensure high yields from non-standard samples, including:

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

Principle

DNeasy and QIAwave DNA 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.

Procedure

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 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 in the DNeasy Blood & Tissue Kit 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 Connect. The DNeasy 96 Blood & Tissue Kit provides high-throughput processing in a 96-well format using the QIAGEN 96-Well-Plate Centrifugation System.

Standard protocols for DNeasy Blood & Tissue Kits can be executed seamlessly via the TRACKMAN Connected system.

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.

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 -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.
