Structural proteins of fixed rabies virus in the suckling mouse brain

Structural proteins of fixed rabies virus grown in the suckling mouse brain were analysed by SDS-polyacrylamide gel electrophoresis (PAGE). The relative content of G protein to L, N and M1 proteins of brain-grown virus was much lower when compared with that of the virus grown in chick embryo fibroblasts. The results indicate that nucleocapsid complexes, consisting of L, N and M1 proteins were the predominant antigens accumulating in the brain.
