title: [Isolation of surface antigens of influenza virus A/Hong Kong 1/68 (H3N2) by density gradient fractionation with a new carboxypolypeptidase (author's transl)].
abstract: Isolation of pure neuraminidase and hemagglutinin from influenza virus A/Hong Kong 1/68 (H3N2) can be achieved using the coupled action of a new carboxypolypeptidase from Streptomyces fradiae and sodium dodecyl sulfate (SDS). Biochemical, physical and physico-chemical studies showed that the two molecules are in pure form and of glycoproteic nature.
