Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Packaged, optimised and ready to use. Expect Better Data.

Overview

• Concentrate circulating DNA into a flexible elution volume ranging from (25 µL – 50 µL)
• Isolate inhibitor-free cell-free circulating DNA
• Compatible with Streck Cell-Free DNA BCT® Tubes
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
• Research use format is also available

These kits provide a fast, reliable and convenient spin column method for the isolation of high quality, high purity and inhibitor-free cell-free circulating DNA (cfc-DNA) from plasma/serum sample. These kits are designed to isolate all sizes of cfc-DNA from either fresh or frozen plasma/serum samples and the purified DNA is eluted into a flexible elution volume ranging from 25 µL to 50 µL. The purified plasma/serum cfc-DNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis, microarrays and NGS.

Background

Plasma/Serum cell-free circulating DNA (cfc-DNA) has the potential to provide biomarkers for certain cancers and disease states as well as fetal DNA in maternal blood. Currently, significant advancements are being made in utilizing cfc-DNA as biomarkers for the early diagnosis, prognosis and monitoring of therapy for several cancer types and autoimmune diseases. Cell-free mitocondrial DNA (cfmtDNA) is also under investigation for its clinical significance. This cfc-DNA is usually present as short fragments of less than 1000 bp. In addition, cell-free fetal DNA has been widely used as a non-invasive method for prenatal diagnosis including early identification of fetal sex, genetic studies for families at high risk for inherited genetic disorders, screening for Rhesus factor, screening for aneuploidy and identification of preeclampsia.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature (15-25°C) for up to 2 years without showing any reduction in performance. Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits contain ready-to-use Proteinase K solution, which is dissolved in a specially prepared storage buffer. The Proteinase K is stable for up to 2.5 years after delivery when stored at room temperature. To prolong the lifetime of Proteinase K, storage at 2–8°C is recommended.
