Viral antigen production and purification. a and b. Virus particles and BEI-inactivated viruses were purified by ultrahigh-speed centrifugation and sucrose gradient centrifugation respectively, and purified viruses were then used for preparation of infected and immune sera. As shown in Fig. 1a and b, the diameter of the virus particles was approximately 30 nm (bar = 200 nm)
