Isolation of an antigenic determinant from flagellar glycoproteins of

A labeled oligosaccharide fraction, obtained by reductive β-elimination of an extract of minus mating-type flagella of , is shown to contain a disaccharide fraction which is bound by an antiserum raised against the sexual agglutination factor present at the flagellar surface of that species. The fraction contains arabinose and galactose. It is argued that galactose and/or arabinose may be a functional constituent of the agglutination factor.
