Omaha, NE – Streck announces Streck Cell-Free DNA Urine Preserve, 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.

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.
