Brevetoxins (PbTx) are a class of cyclic polyether compounds produced by certain algae such as Karenia brevis. K. brevis can produce Brevetoxins in large quantities during an algae bloom which then pose a major health threat and are important to monitor and mitigate. Brevetoxins are the causative agent of Neurotoxic Shellfish Poisoning (NSP).

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.

Up to 30 days at room temperature (15-25°C) Up to 8 days at 37°C
Length of cf-RNA Preservation
Up to 30 days at room temperature (15-25°C)
Length of CTCs Preservation

Storage Conditions and Product Stability
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.
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.
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.
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)
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.

Genotype directly from RNA samples. RNA reverse transcription and cDNA PCR genotyping simultaneously in a single, one-step reaction.
About
ProbeSure OneStep RT-PCR Master Mix combines reverse transcription (RT) and PCR in a single step. This advanced master mix simplifies workflows by eliminating the need for separate reactions for reverse transcription of RNA to cDNA, and PCR amplification from the newly generated cDNA.
ProbeSure OneStep RT-PCR Master Mix is highly efficient and sensitive, enabling detection of low-abundance RNA targets, particularly useful for applications such as gene expression analysis and viral RNA detection. ProbeSure OneStep RT-PCR Master Mix demonstrates robust performance across a wide range of RNA templates and can be employed for both routine and challenging samples.
