Highlights
- Effectively preserves DNA and RNA in urine at ambient temperatures
- Facilitates pelleting of both cellular and cell-free nucleic acids from large volume urine samples
- Inhibits microbial growth during long-term (cold-free) storage of urine samples
Description
Q1: How long can urine samples be stored after addition of UCB?
Urine samples will be stabilized for a minimum of 30 days at ambient temperature.
Q2: Does UCB preserve nucleic acids like DNA/RNA Shield?
Yes, UCB will preserve DNA and RNA integrity.
Q3: How do I purify DNA/RNA from urine samples stabilized with UCB?
Mix urine thoroughly and centrifuge at 3000 x g for 15 minutes to form a urine pellet. Purify urine nucleic acid directly from urine pellet using Quick-DNA Urine kit(D3061) or Quick-RNA Miniprep Plus kit (R1057, R1058).
Researchers studying WNV and ZIKV in urine face profound viral RNA loss and major difficulties in viral RNA isolation exhibiting a need for optimal preservation for long-term storage. UCB was used to minimize degradation of WNV RNA in urine during storage. As well as extend the period of detection and detect ZIKV at later time points after infection.
