Streck® Urine Preserve
Streck Urine Preserve is a ready-to-use liquid reagent that stabilizes nucleic acid targets in urine for up to 7 days at 6 °C to 37 °C. Each single-use vial can stabilize 25 mL to 100 mL of urine. Once isolated, the nucleic acid targets are suitable for use in many downstream analytical methods such as qPCR, ddPCR, and others.

Once isolated, the nucleic acid targets are suitable for use in many downstream analytical methods such as qPCR, ddPCR, and others. Streck Urine Preserve enhances the stability of nucleic acid targets in urine and limits the lysis of cellular material which can lead to the contamination of true cell-free targets present at the time of sample collection. Streck Urine Preserve also inhibits the nuclease mediated degradation of nucleic acids during room temperature storage.
The reagent maintains cellular and non-cellular sources of nucleic acids in order to limit changes associated with sample handling, shipping, and field collection. The product also enables ease of use such as batch processing and bulk handling while removing the need for immediate processing or cold chain management.
