Product Details

The PAXgene Blood DNA system consists of PAXgene Blood DNA Tubes, for blood collection and stabilization, and the PAXgene Blood DNA Kit, for DNA purification in a single-tube procedure.

Performance

DNA isolated using the PAXgene Blood DNA System has an A260/A280 ratio of 1.7–1.9. Fragments are 20–200 kb in size, with an average length of 50–150 kb (see figure " High quality and high molecular weight of genomic DNA"). Average DNA yields are 150–500 µg, depending on the number of nucleated cells present in the blood sample. Purified DNA can be used for PCR and quantitative, real-time PCR (see figure " Efficient multiplex PCR of 3 mitochondrial genes").
See figures

Principle

The PAXgene Blood DNA System is an integrated and standardized system for collection and stabilization of whole blood specimens and isolation of their genomic DNA. The system requires the combined use of PAXgene Blood DNA Tubes for blood collection and stabilization, followed by DNA isolation using the PAXgene Blood DNA Kit.

Blood is collected into PAXgene Blood DNA Tubes, which contain a proprietary blend of reagents that both prevents blood coagulation and stabilizes white blood cells. Blood samples can be stored in the tubes for up to 14 days at room temperature. DNA is isolated from the tubes using appropriate buffers supplied in the PAXgene Blood DNA Kit. Highly pure genomic DNA is obtained, suitable for use in a wide range of downstream applications.

Procedure

The PAXgene Blood DNA procedure is shown in the flowchart " PAXgene Blood DNA procedure". Blood samples (8.5 ml) are collected in PAXgene Blood DNA Tubes, where they may be stored or transported. For DNA isolation, the blood is transferred to processing tubes (supplied already filled with cell lysis buffer), and the solution is mixed to lyse red and white blood cells. Cell nuclei and mitochondria are pelleted by centrifugation, washed, and resuspended in digestion buffer. Protein contaminants are removed by incubation with a protease. DNA is precipitated in isopropanol, washed in 70% ethanol, dried, and resuspended in resuspension buffer.

See figures

Applications

The DNA can be used in a wide range of downstream applications, including:

  • PCR and quantitative, real-time PCR
  • Southern blotting
  • SNP genotyping
  • Pharmacogenomic studies
  • SNP discovery and Validation

Blood samples in PAXgene Blood DNA Tubes can be stored at room temperature (18–25°C) for up to 14 days or at 2–8°C for up to 28 days. For long-term storage, samples should be frozen at –20°C.

FAQ ID - 3490
3497 - What is the expected purity and size of DNA extracted using the PAXgene Blood DNA kit?

The typical A260/A280 ratio is from 1.7 to 1.9. The DNA molecules are up to 200 kb in size, with fragments of 50–150 kb predominating.

FAQ ID - 3497
Do I have to use a blood collection set with the PAXgene Blood DNA Tube?

No, a blood collection set is not required to use PAXgene Blood DNA Tubes. Further information on phlebotomy technique with PAXgene Blood DNA Tubes IVD can be found in the product handbook.

FAQ ID - 3484
Can the PAXgene Blood DNA Tubes be stored at 4°C?

Yes, the PAXgene Blood DNA Tubes can be stored at 4°C for up to 28 days after blood collection.

FAQ ID - 3493
Can PAXgene Blood DNA Tubes be stored at higher than room temperature (18–25°C)?

Yes, samples in PAXgene Blood DNA Tubes can be stored at 30°C for up to 3 days after blood collection. However, it is not recommended to store blood samples at temperatures higher than 30°C and storage at high temperatures should not exceed 3 days.
