STUDIES ON EPIDEMIC INFLUENZA VIRUS : THE NATURE AND PROPERTIES OF THE COMPLEMENT-FIXING ANTIGEN.
Evidence is presented which indicates that influenza virus elaborates a soluble antigen. The antigen is considerably smaller than the virus and can be separated from it, but the virus has not been washed free of antigen. The properties of the antigen suggest that it is an unstable protein of relatively large size.
