原理

PAXgene Blood DNA System是整合的标准化体系，用于收集和稳定全血样本并分离基因组DNA。该体系通过PAXgene Blood DNA Tubes收集和稳定血液，并使用PAXgene Blood DNA Kit纯化DNA。

PAXgene Blood DNA Tubes包含可防止血液凝结以及可稳定白细胞的混合试剂，用来收集血液。血液样本可在室温下在管中储存长达14天。用PAXgene Blood DNA Kit中提供的缓冲液获得的高纯度的基因组DNA适合各种下游应用。

程序

PAXgene Blood DNA操作步骤如流程图" PAXgene Blood DNA procedure"所示。血液样本（8.5 ml）由PAXgene Blood DNA Tubes收集，并储存或运输。如需纯化DNA，则将血液转入处理管中（已预充细胞裂解缓冲液），将溶液混合，裂解红细胞和白细胞。细胞核和线粒体通过离心收集、洗涤，重悬于裂解缓冲液中。蛋白污染物经蛋白酶孵育后去除。DNA用异丙酮沉淀、70%乙醇洗涤、干燥，并重悬于缓冲液。

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.

FAQ

You can find additional information relating to the PreAnalytiX PAXgene products on the PreAnalytiX website .

FAQ ID - 3515

Buffer BG4 consists of 10 mM Tris·Cl, pH 8.5.

FAQ ID - 3501

No. DNA purified with the PAXgene Blood DNA System is free of detectable RNA contamination. In contrast to commercial salting out methods, additional RNase digestion steps are not necessary.

FAQ ID - 3499

See subsequent FAQs for information about storage interval and temperature. Each laboratory should validate shipping procedures.

FAQ ID - 3507

Samples in PAXgene Blood DNA Tubes can be stored at room temperature (18–25°C) for up to 14 days after blood collection.

FAQ ID - 3508

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

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.

FAQ ID - 3509

The typical A₂₆₀/A₂₈₀ ratio is from 1.7 to 1.9.

FAQ ID - 3511

Yield of genomic DNA varies depending on the white blood cell count of the patient blood sample, the extraction method, and the elution volume. However, DNA yield typically ranges between 16–135 µg/ml whole blood. Specifically, DNA yields from magnetic bead-based extraction on the QIAsymphony ranges between 16.9–51.7 µg/ml whole blood, from silica membrane-based extraction on the QIAcube 17.1–45.8 µg/ml whole blood, and from salting-out precipitation 4.9–53.7 µg/ml whole blood.

FAQ ID - 3510

Yes, mitochondrial and genomic DNA are both isolated.

FAQ ID - 3498

No. The volume of Buffer BG1 (lysis buffer) prefilled in the processing tubes, and all the other buffer volumes are optimized for use with blood from one PAXgene Blood DNA Tube.

FAQ ID - 3500

To date, DNA purified from blood samples in PAXgene Blood DNA Tubes has been successfully tested for use in PCR, including multiplex PCR.

FAQ ID - 3512

DNA purified using the PAXgene Blood DNA System should be dissolved in Buffer BG4 and stored at 2–8°C. For long-term storage, DNA can be stored at –20°C but multiple freezing and thawing cycles should be avoided.

FAQ ID - 3502

Yes. After dissolving the nuclei pellet in digestion buffer, Buffer BG3 (step 7), samples can be stored up to 7 days at 2–8°C or for one day at room temperature (18–25°C). The protocol can also be interrupted after adding isopropanol (step 10).

FAQ ID - 3503

So far, we have shown that DNA purified using the PAXgene Blood DNA System can be used in PCR, including long range and multiplex PCR, restriction digestion and Southern analysis, as well as in various SNP detection procedures including,TaqMan®, LightCycler and Masscode technologies.

FAQ ID - 3506

Do not add bleach or acidic solutions directly to the sample preparation waste. CAUTION: The sample preparation waste contains guanidinium hydrochloride from Buffer BG3, which can form highly reactive compounds when combined with bleach. For more information please consult the appropriate material safety data sheets (MSDS).

FAQ ID - 3505

The system is designed for use only with human blood samples.

FAQ ID - 3504

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.
