cf-DNA Preservative Tubes Dx

Norgen's cf-DNA Preservative Tubes Dx are closed, evacuated plastic tubes for the collection and the preservation of cell-free circulating DNA/circulating tumor DNA 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 Circulating DNA Purification Kits (Slurry Format) enables the purification and concentration of an inhibitor-free cell-free circulating DNA/circulating tumor DNA in a very small elution volume that is compatible with any downstream application.These tubes are ideal for collecting and preserving cf-DNA samples for in vitro diagnostic use for medical purposes.PerformanceNorgen's cf-DNA Preservative Tubes Dx abridge the collection/processing of whole blood for the subsequent purification of cell-free circulating DNA. The cf-DNA Preservative Tubes Dx preserve and inhibit the programmed cell-death (apoptosis) of the blood, hence preventing the release of intracellular DNA into plasma (see Figure 4). Moreover, the cell-free circulating DNA/circulating tumor DNA levels are stable for up to 30 days at room temperature or up to 8 days at 37°C (Figure 1 and Figure 5). Whole blood samples can be shipped and stored at room temperature for the subsequent processing of plasma.Plasma samples produced from the whole blood sample collected into Norgen’s cf-DNA Preservative Tubes Dx and purified using Norgen's Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen's Plasma/Serum Circulating DNA Purification Kits (Slurry Format) yield concentrated, high-quality and inhibitor-free cf-DNA/ct-DNA for any downstream application assays, including PCR, qPCR, methylation-sensitive PCR, Southern Blot analysis, microarrays and NGS.WorkflowCollection and Mixing Instructions To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video NOTE: This product is not available for sale in the United States.
