Introduction
The EZgeneTMĀ Viral DNA/RNA kit provides an easy and reliable method for isolating total viral DNA/RNA from plasma, serum, whole blood, urine and cell culture supernatant. This procedure has been tested for isolating nucleic acids from Hepatitis A, Hepatitis C and HIV. The isolated DNA/RNA can be used for PCR, RT-PCR and other downstream applications.
Storage and Stability
All other components can be stored at room temperature. All kit components are guaranteed for 1 year from the date of purchasing.

Before Starting
Prepare all components and get all necessary materials ready by examining this instruction booklet and become familiar with each step.
Important
- Ā Add 1% volume of Ī²-mercaptoethanol to Buffer PLY before use and store at 4Ā oC.
- Ā Add 8 mL (VR6511-00) or 60 mL (VR6511-01) or 96 mL (VR6511-02) 100% ethanol into each Wash Buffer bottle before use.
Materials supplied by users
- Ā Tabletop microcentrifuge
- Ā 1.5 mL sterile tubes
- Ā 100% ethanol
Note: Perform all steps including centrifugation at room temperature
Trouble Shooting Guide
| Problem | Possible reason | Suggested Improvement |
| Low A260/A280Ā ratios
|
Protein contamination | Do a Phenol:Chloroform extraction. Loss of total RNA (up to 40%) should be expected. |
| Low A260/A280Ā ratios
|
Guanidine Thiocyanate contamination
|
Add 2.5 volumes of ethanol and 0.1M NaCl (final concentration) to precipitate RNA. Incubate for 30 min at -20Ā°C. Centrifuge at 13,000 rpm for 15 min at 4Ā°C. Resuspend the RNA pellet in DEPC-treated water. |
| Low Yield | RNA in sample degraded
|
Freeze samples immediately in liquid nitrogen and store at -70Ā°C after collect it. |
| Low Yield | The binding capacity of the membrane in the spin column was exceeded | Use of too much sample exceeding the binding capacity of spin column will cause the decreasing of total RNA yield. |
| Low Yield | Ethanol not added to buffer | Add ethanol to the Wash Buffer. |
| Genomic DNA contamination
|
Too much total RNA sample was used in RT-PCR. | Reduce total RNA amount used in RT-PCR to 50-100 ng. |
