title: Non-specific inhibitory fraction for hemagglutination of some togaviruses obtained from Swiss albino mouse brain.
abstract: A fraction from Swiss albino mouse brain homogenate obtained by DEAE cellulose chromatography showed a non-specific hemagglutination-inhibitory property for some Togaviruses. Evidence are presented indicating that the inhibitory property is related to a protein-rich fraction with sialic acid as an active group.
