Cell-Free DNA Urine Preserve

Cell-Free DNA Urine Preserve is a general purpose reagent in a ready-to-use liquid format that stabilizes all the cell-free DNA in samples for up to 7 days at 6 °C to 37 °C. Once isolated, the cfDNA is suitable for many downstream applications such as qPCR, ddPCR, and other methods used to profile circulating DNA.

Cell-Free DNA Urine Preserve

Cell-Free DNA Urine Preserve is a general purpose reagent in a ready-to-use liquid format that stabilizes cell-free DNA (cfDNA) in urine samples. Samples treated with Cell-Free DNA Urine Preserve are stable up to 7 days at 6 °C to 37 °C. The cfDNA isolated can be used for many downstream applications such as qPCR, ddPCR, and other methods used to profile circulating DNA. The reagent stabilizes all cellular components, including red blood cells and white blood cells present at the time of collection. Cell-Free DNA Urine Preserve enhances the stability of cfDNA and eliminates the lysis of nucleated blood cells and release of cellular genomic DNA which could interfere with accurate cfDNA analysis. Treatment of urine with the liquid preservation reagent also inhibits nuclease mediated nucleic acid degradation during room temperature storage.
