Description : The EZgeneTM Viral RNA Kit provides an easy and reliable method for isolating total viral RNA from plasma or serum while enzyme inhibitors and other contaminates completely removed. This procedure has been tested for isolating nucleic acids from Hepatitis A, Hepatitis B, Hepatitis C and HIV. This kit can also be used to isolate viral DNA/RNA from urine and cell culture supernatant. All other components can be stored at room temperature. All kit components are guaranteed for 12 months from the date of purchasing.

Note: Perform all steps including centrifugation at room temperature Problem Possible reason Suggested Improvement Low A260/A280 ratios Protein contamination Do a Phenol: Chloroform extraction. Loss of total RNA (up to 40%) should be expected. Guanidine Thiocyanate contamination Add 2.5 volumes of ethanol and 0.1M NaCl (final concentration) to precipitate RNA. Incubate for 30 min at -20 oC.. Centrifuge at 10,000 g for 15 min at 4 oC.. Resuspend the RNA pellet in DEPC-treated water. Low Yield RNA in sample degraded Freeze samples immediately in liquid nitrogen and store at -70 oC. after collect it. The binding capacity of the membrane in the spin column was exceeded Use of too much tissue sample exceeding the binding capacity of spin column will cause the decreasing of total RNA yield. Ethanol not added to buffer Add ethanol to the RNA Wash Buffer before purification. Operating Protocol :Introduction
