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.

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the udder is mainly caused by infection of various bacteria. One of such mastitis bacteria, Streptococcus agalactiae, is highly infectious and causes mainly subclinical infections, which are not identified by the herdsman. As a result, S. agalactiae can spread widely within a herd, causing immediate loss due to reduced milk. S. agalactiae is a gram-positive bacteria belonging to the Group B streptococci. Traditional cultural identification of S. agalactiae is based on S. agalactiae being beta-hemolytic as well as presence of group B Lancefield antigen and by its ability to hydrolyze sodium hippurate.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

DBCO-PEG12-Maleimide is a PEG linker containing a DBCO moiety and a terminal primary maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
