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 to limit changes associated with sample handling, shipping and field collection.
Product Description
Streck Urine Preserve is a liquid reagent that stabilizes nucleic acid targets in 25 mL to 100 mL of urine for up to 7 days at 6 °C to 37 °C. This preservative limits the lysis of cellular material, which can lead to the contamination of true cell-free targets present at the time of sample collection, and inhibits the nuclease mediated degradation of nucleic acids during room temperature storage. With Streck Urine Preserve, you can implement batch processing and bulk handling while eliminating the need for immediate processing or cold chain management…

For Research Use Only. Not for use in diagnostic procedures.
A CE version is also available, not for sale in the U.S.
Cold chain free – Transport samples at room temperature

Features
- 7-day sample stability when stored at 6 °C to 37 °C
- Contains a PCR compatible blue dye to provide visual reassurance that reagent has been added
- Available in single-use containers to treat 25 mL to 100 mL of urine
- Isolated nucleic acids are suitable for many downstream applications
Benefits
- Can easily be added to urine samples at time of collection
- Reduces the need for immediate sample extraction
- Room temperature storage reduces costs and complications associated with cold chain shipping

The art of obtaining a high yield of cell-free DNA from urine
Urine is becoming increasingly important in liquid biopsy research; however, the detection of circulating cell-free DNA (cfDNA) in urine samples remains a challenge.
Key learning objectives from this webinar:
- Overcome the challenges that occur when working with urine samples
- Learn tips and tricks regarding the pre-analytical conditions in urine samples

Stabilization of cfDNA in Urine Using a Preservative Reagent During Sample Processing, Transport, and Storage
Streck Cell Preservative is formerly known as Cyto-Chex
Cyto-Chex stabilized CD markers on the lymphocytes in bone marrow samples for up to 72 hours. The flow cytometric diagnosis is …
