immunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of [ 35s ] methionine-labeled proteins from wild-type vector-infected cells with heterospecific n2 antibody showed that the product of the cloned na dna comigrated with glycosylated na from influenza virus-infected cells , remained associated with internal membranes of cells fractionated into membrane and cytoplasmic fractions , and could form an immunoprecipitable dimer .
