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.

These kits are designed to clean-up and concentrate RNA (including miRNA) from TRIzol® and TRI Reagent®, enzymatic reactions, in vitro transcription, labelling reactions, etc. These are robust kits for all clean-up and concentration purposes for up to 35 µg of RNA in solution. The purified RNA is of the highest purity and integrity, and can be used in a number of downstream applications. These kits purify all sizes of RNA, from large mRNA and ribosomal RNA down to miRNA, siRNA and lncRNA.
Norgen’s RNA Clean-Up and Concentration Kit provides a rapid method for the purification, cleanup and concentration of up to 35 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment and labeling. The kit elutes RNA in 20 µL. Complete 10 purifications in 20 minutes.
Norgen’s RNA Clean-Up and Concentration 96-Well Kit provides a rapid method for the purification, cleanup and concentration of up to 50 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment and labeling. The kit elutes RNA in 75 µL. Complete 10 purifications in 30 minutes.
Norgen’s RNA Clean-Up and Concentration Micro-Elution Kit provides a rapid method for the purification, cleanup and concentration of up to 10 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment, labeling and in vitro transcription. This kit is made for eluting RNA in smaller volumes of 8 µL for all types of downstream applications, for the highest concentration of RNA sample. Complete 10 purifications in 20 minutes.
