Q1: What sample types is DNA/RNA Shield suitable for?
DNA/RNA Shield can be used on upper and lower respiratory human specimens.
Q2: How long can samples be stored samples in DNA/RNA Shield at ambient temperature?
RNA > 1 month
Q3: Can I still use DNA/RNA Shield if a precipitate has formed?
This can happen on occasion due to transport or storage at lower temperatures. The reagent functionality is not affected; however, the precipitate can be resolved by heating the reagent to >37 °C.
Q4: Do I need to homogenize the sample in DNA/RNA Shield prior to storage?
No, tissues do not need to be homogenized.
Q5: Is DNA/RNA ShieldTM compatible with bleach (sodium hypochlorite)?
Avoid mixing the reagent and bleach (sodium hypochlorite) or other strong oxidizing agents and acids. Clean up any accidental spills with water first.
Q6: Can the swab be submerged prior to collecting?
For any biological sample collection (nasal, throat, etc.), use a sterile swab for collection and then deposit it into DNA/RNA Shield. For application-specific questions, please reach out to technical support.
“We extracted RNA from cells suspended in DNA/RNA Shield with the Direct-zol miniprep set from Zymo (using Trizol). It worked perfect for us.”
- Mariska B. (University of Amsterdam)
“I did an assay using RNA/DNA shield and it works perfect. The product have excellent reproducibility when stored at 4°C for up to a month.”
- Maha AE. (University of Florida)
“We use DNA/RNA shield and it works well with adults mosquitoes, larvae, eggs. We store it at RT for weeks and at -4°C or -20°C for months, never saw any DNA degradation.”
- Umberto P. (University of Pavia)
