The TECO® Urine Stabilizing Buffer (10 ml) is a protein-rich urine stabilizing buffer designed to preserve urinary proteins. The tube contains 10ml of buffer. Stabilizing buffer should be added in a 1:5 ratio with each urine sample. Urine samples should ideally be added to a sufficient amount of buffer within 12 hours of collection. They can then be stored at:
- 2-8˚C for one week,
- -20˚C for up to 28 days, or
- -70˚C for one year*
*Avoid repeat freeze-thaw cycles.
Note: Stabilizing buffer has not been shown to interfere with biomarker assays. Nonetheless, it is recommended that individual labs validate the urine collection solution with their assay procedures.
