Introduction

This product provides fast and easy methods for purification of total DNA for reliable PCR and Southern blotting. Total DNA(e.g., genomic, viral, mitochondrial) can be purified from small volume of blood, tissue and dry blood spots.

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mmTris, pH9.0, 0.5mm EDTA).

Advantages

• Fast – several samples can be extracted in 20 minutes (after digestion)
• High purity – purified DNA can be directly used in various downstream applications
• High recovery – DNA can be recovered at the level of PG
• Good repeatability – silica technology can obtain ideal results every time

Storage and Stability

Carrier RNA and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under theseconditions.

Overview

• CE-IVD marked in accordance with EU Directive 98/79/EC
• Ideal for use in in vitro diagnostic workflows
• Fixative-free preservative, no cross-linking of DNA
• Preserve cf-DNA/ct-DNA for 30 days at ambient temperature and for up to 8 days at 37°C.
• Preserve cf-RNA for 30 days at ambient temperature
• Preserve Circulating Tumour Cells (CTCs) for 14 days at ambient temperature
• No plasma volume loss after shipping/transportation
• Prevent hemolysis allowing better separation of plasma
• Prevent apoptosis of blood cells and fragmentation of genomic DNA
• Produce high quality/quantity of plasma cf-DNA/ct-DNA/cf-RNA
• Vacuumed to draw 8.4 mL of blood in 10 mL tubes
• The procedure for plasma isolation using this kit is compliant with ISO 20186-3:2019

Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx 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. 

These tubes are ideal for collecting and preserving cf-DNA and cf-RNA samples for in vitro diagnostic use for medical purposes.

Performance

Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx 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 Dx 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.

Storage Conditions and Product Stability

1. When stored at 15-30°C, unfilled Norgen cf-DNA/cf-RNA Preservative Tubes Dx 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 Dx.
3. Do not freeze unfilled Norgen cf-DNA/cf-RNA Preservative Tubes Dx for long term storage over 10 days. Freezing unfilled tubes may lead to loss of vacuum and precipitation may occur.
4. Cell-free DNA in blood samples collected in Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx is stable for up to 30 days when stored at room temperature (15-25°C)
5. Cell-free DNA in blood samples collected in Norgen’s cf-DNA/cf-RNA Preservative Tubes Dx 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 Dx 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 Dx are stable for up to 14 days at room temperature (15-25ºC).
