Double Cesium Chloride Gradient Purification of a Recombinant Adenovirus

Amplified viral stocks should be purified in order to:

1. Remove all defective particles from the preparation,

2. Remove the condition media containing undesired contaminants as well as serum,

3. Resuspend the virus in a buffer more suitable for later use and long term storage,

4. Concentrate the virus to high levels.
