[Isolation of the protein component of the soluble Tamiami virus antigen by using affinity chromatography on IgG-cellulose].

IgG to Tamiami virus is covalently bound to metaaminobenzylcellulose by nitrogen coupling. An immune sorbent was prepared and used to treat the virus soluble antigen (SA); a protein responsible for the serological properties of SA was isolated. Electrophoretic analysis in polyacrylamide gel showed this protein to be a nucleocapsid protein of the virion.
