Urine Cell-Free Circulating DNA Purification Midi Kit

About this product

Isolate all sizes of circulating DNA from fresh, preserved or frozen urine samples Isolate viral DNA Versatile urine input volumes Concentrate circulating DNA into flexible elution volumes Isolate inhibitor-free cell-free circulating DNA Compatible with Norgen’s Urine Preservative and other commercially available urine preservatives Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix These kits provide a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating DNA as well as viral DNA from fresh, preserved or frozen urine samples. All components for the purification are provided in one convenient and fast kit for the easy processing of small input volumes of bodily fluids. The purified urine DNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis, Microarrays and NGS. Background Recent evidence indicates that cell-free circulating DNA (cf-DNA) contains valuable information for the discovery of biomarkers that can help with early detection of certain cancer types and for monitoring the disease status. The advantage for using urine as a source for cancer biomarkers is that it can be acquired in large quantities without using invasive procedures. In addition, repeated sampling from the same individual is applicable, which facilitates longitudinal studies. There are many advantages favouring the use of urinary nucleic acids for cancer biomarker discovery over blood, tissue samples or other bodily fluids, including: (1) urine is non-infectious for HIV and less infectious for many other pathogens; (2) the profile of urinary nucleic acid is similar to that in plasma or serum; (3) nucleic acid purification from urine is technically much easier because of its low protein concentration (1000-fold lower than blood) . Urine cell-free circulating DNA (cf-DNA) has been utilized for the early diagnosis, prognosis and monitoring of therapy for several cancer types and autoimmune diseases, as well as for investigating fetal DNA that is normally present in the maternal blood. This cf-DNA is usually present as short fragments, generally between 150 and 250 bp or its duplicates, and is derived either from the apoptotic process, necrotic process or from the fetus. Urine Cell-Free Circulating DNA Purification Mini Kit For sample volumes ranging from 250 µL to 2 mL.
