Norgen’s cf-DNA/cf-RNA Preservative Tubes are closed, evacuated plastic tubes for the collection and the preservation of cf-DNA, circulating tumor DNA, cf-RNA and circulating tumor cells in human whole blood samples during storage and shipping. Using these tubes in combination with Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen’s Plasma/Serum RNA Purification Kits enables the purification and concentration of an inhibitor-free cf-DNA/ct-DNA/cf-RNA in a very small elution volume. Plasma recovered from Norgen’s cf-DNA/cf-RNA Preservative Tubes is also compatible with any other cf-DNA and/or cf-RNA purification method. The purified cf-DNA, ct-DNA and cf-RNA are compatible with any downstream application assays, including PCR, qPCR, rt-qPCR, methylation-sensitive PCR, Southern Blot analysis, gene expression analysis, microarrays and NGS.

This product is for research use only and not for use in diagnostic procedures.

Performance

Norgen’s cf-DNA/cf-RNA Preservative Tubes abridge the collection/processing of whole blood for the subsequent purification of cf-DNA and/or cf-RNA. The cf-DNA/cf-RNA Preservative Tubes preserve and inhibit the programmed cell-death (apoptosis) of the blood, hence preventing the release of intracellular DNA/RNA into plasma. Whole blood samples can be shipped and stored at room temperature for the subsequent processing of plasma. The cf/ct DNA and cf-RNA levels are stable for up to 30 days at room temperature. The cf-DNA is also stable for up to 8 days at 37°C. When blood collected on Norgen’s cf-DNA/cf-RNA tubes is processed for plasma recovery no buffy coat will be generated and the Circulating tumor cells (CTCs) will be located at the bottom of the tube with the blood sediment. CTCs are stable for 14 days at room temperature where it can be extracted from the blood sediment or from whole preserved blood for cell sorting or for cf/DNA or cf-RNA purification.

Plasma samples produced from the whole blood sample collected into Norgen’s cf-DNA/cf-RNA Preservative Tubes and purified using Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen’s Plasma/Serum RNA Purification Kits yield concentrated, high-quality and inhibitor-free cf-DNA/ct-DNA or cf-RNA for any downstream application.

Storage Conditions and Product Stability

1. When stored at 15-30°C, unfilled Norgen cf-DNA/cf-RNA Preservative Tubes are stable through the expiration date.  See tube label for expiry date.
2. Short-term storage/shipping at -20°C to 37°C for up to 10 days is acceptable for unfilled Norgen cf-DNA/cf-RNA Preservative Tubes.
3. Do not freeze unfilled Norgen cf-DNA/cf-RNA Preservative Tubes for long term storage over 10 days. Freezing unfilled tubes may lead to loss of vacuum and precipitation may occur.

5. Cell-free DNA in blood samples collected in Norgen’s cf-DNA/cf-RNA Preservative Tubes is stable for up to 8 days when stored at 37ºC.
6. Cell-free RNA in blood samples collected in Norgen’s cf-DNA/cf-RNA Preservative Tubes is stable for up to 30 days when stored at room temperature (15-25°C)
7. Circulating tumor cells (CTCs) in blood samples collected in Norgen’s cf-DNA/cf-RNA Preservative Tubes are stable for up to 14 days at room temperature (15-25ºC).

Introduction

This product is suitable for rapid extraction of DNA from tissue, cells, blood, saliva, swabs, blood spots, semen and other clinical samples. DNA can be used directly for PCR, quantitative PCR, Southern Blot, test of virus DNA and so on.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Advantages

• High purity – OD 260 / 280 : 1.7- 1.9, OD 260 / 230 : 1.5 – 2.0
• Economy – less than 50% of the price of Qiagen and other imported products
• High yield – most optimal process, ensuring the recovery up to 90%
• Strong processing ability – samples including animal blood, cultured cells, animal tissues, etc.

Storage and Stability

Proteinase K, RNase A, MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

Biotin-PEG8-alkyne is a PEG linker containing a biotin group and a terminal alkyne. Biotin is useful for affinity-based applications such as pull-down assays while terminal alkynes are used in copper (I) click chemistry with azide groups on a target molecule. The inclusion of a PEG linker in this molecule improves its solubility in water.
