Streck Cell-Free DNA Urine Preserve is an innovative, easy-to-use liquid preservative that stabilises cfDNA in urine samples.
Samples treated with Cell-Free DNA Urine Preserve are stable for up to 7 days when stored at 6°C to 37°C, eliminating the adverse effects time, storage and transport conditions have on sample integrity.
The discovery of cell-free DNA (cfDNA) in peripheral blood has been extensively studied and documented. The detected DNA can originate from a tumour, fetus or transplanted organs. More recently, it has been determined that small amounts of cfDNA can pass the kidney barrier and end up in urine.
Urine is a truly non-invasive source of cfDNA, a clear advantage over peripheral blood. The cfDNA isolated can be used for various applications, including disease monitoring (diagnosis, prognosis and treatment efficacy) and as a screening tool for hereditary conditions.
Cell-Free DNA Urine Preserve is contained in easy-to-dispense, one-time use vials. The blue PCR compatible dye provides visual reassurance that reagent was added. The 5.0mL of liquid reagent is appropriate to preserve individual urine sample volumes from 25mL to 100mL.
Streck Cell-Free DNA Urine Preserve has 24-month shelf life from the date of manufacture.
