This product contains a high concentration of virus and viral components. The preparation also contains some cellular material suspended in Tissue Culture Media.
Optimally infected monolayers are harvested, disrupted by sonication and subjected to low speed centrifugation. The clarified cell lysate is pooled with supernatant from the infected culture and concentrated using crossflow ultrafiltration with a 30,000 molecular cutoff.
The antigen preparation is inactivated using gamma radiation.
