NucleoSpin RNA Virus is designed for the isolation of viral nucleic acids from serum, plasma, or any cell-free biological fluids. The kit features a special type of membrane which has a high binding capacity for viral RNA or DNA. The procedure is rapid and easy; the lysate is incubated for 5–10 min and applied to the NucleoSpin column. After two wash steps to remove contaminants, the viral RNA or DNA can be eluted with water or low-salt buffer. The kit contains all necessary buffers, spin columns, and detailed protocols.
