ZellX^® Viral RNA extraction Kit is designed for the quick purification of viral RNA from cell-free samples such as serum, plasma, urine, and other body fluids, cell culture supernatants and rinse liquid from swabs samples. The viral RNA molecules bind to the silica-based membrane, and impurities such as proteins and nucleases are removed by thorough washing with Wash Buffer. The RNA is then eluted in sterile, RNase free water.

The isolated viral RNA is ready to use and should be stored at -70°C. The procedure can be used for isolation of viral RNA from a broad range of viruses. However, performance cannot be guaranteed for every virus species and must be validated by the customer. The quantity of purified viral RNA depends on different parameters including the sample type, virus titer, sample source, transport, storage, and age. Our Kit additionally contains carrier RNA that improves binding and recovery of low-concentrated viral RNA.
