Cell-Free DNA Urine Preserve

Streck Cell-Free DNA Urine Preserve is a formaldehyde-free liquid reagent that stabilizes cell-free DNA (cfDNA) in urine. Samples treated with Cell-Free DNA Urine Preserve are stable up to 7 days at 6 °C to 37 °C, ensuring sample integrity for cfDNA extraction and testing, such as prenatal diagnosis, disease diagnosis and treatment efficacy monitoring, and organ transplant rejection monitoring. The reagent stabilizes all cellular components including red blood cells, white blood cells, and proteins present at the time of collection, allowing for additional downstream urinalysis testing.

Consistent Results
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.

Improved Logistics

Cell-Free DNA Urine Preserve is easily added to urine samples at time of collection, allowing for adequate time to transport and store prior to cfDNA extraction.

Convenient Workflows
Cell-Free DNA Urine Preserve allows for cfDNA extraction and standard urinalysis testing to be done within existing laboratory workflows without compromising sample integrity.

Cell-Free DNA Urine Preserve is packaged in single use 5 mL plastic ampules with the appropriate amount of reagent to preserve individual urine sample volumes of 25 mL to 100 mL.  The product is available in 20-ampule and 5-ampule configurations.
