In vitro examination of some biological activities of glycoprotein antigens of the PI3 virus

On the basis of the results obtained we have reached the following conclusions: (1) The fusional activity of separated activated glycoprotein antigens of the PI3 virus (++) is twice as high as the fusional activity of the same ones within complete viral particles (+). (2) The hemagglutinating activi...

Summary:On the basis of the results obtained we have reached the following conclusions: (1) The fusional activity of separated activated glycoprotein antigens of the PI3 virus (++) is twice as high as the fusional activity of the same ones within complete viral particles (+). (2) The hemagglutinating activity of the samples of separated glycoprotein subunits (512 HJ/0.1 ml) is twice higher than in the samples of complete purified PI3 viruses (256 HJ/0.1 ml). (3) Our methods for purification and separation of glycoprotein antigens from outer envelopes of the PI1 virus enable us to preserve and increase the biological activities of immunologically significant H, N and F.
