Norgen’s Urine Preservative is designed for the rapid preservation of DNA, RNA, microRNA and proteins from fresh urine samples. The Urine Preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Urine Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins.
Norgen’s Urine Preservative is available in 2 convenient formats:
1. Urine Preservative Single Dose Ampules

The user simply collects 5 – 50 mL of urine into a urine collection container and adds the contents of the Urine Preservative Single Dose (Cat# 18124). The urine and preservative are then mixed, and the urine nucleic acids and proteins are preserved at room temperature.
