Hepatitis B virus, hepatitis non‐A, non‐B virus and hepatitis delta virus in lyophilized antihemophilic factor: Relative sensitivity to heat
Robert H. Purcell, John L. Gerin, Hans Popper, William T. London, John Cicmanec, Jorg W. Eichberg, Jack Newman, Michael E. Hrinda – 1 November 1985 – Lyophilized plasma derivatives are more stable to heat than when they are in the liquid state. Commercial Factor VIII (antihemophilic factor) was seeded with a measured quantity of hepatitis B virus. The contaminated material was then lyophilized and subjected to heat of 60°c for 30 hr. Chimpanzees were inoculated with the heat‐treated antihemophilic factor or sham‐treated antihemophilic factor that had been held at 4°c.
