Cf-DNA/cf-RNA Preservative Tubes Dx

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.
