[Molecular study in polyacrylamide gel of polypeptides of several strains of rabies virus]

Comparative study of structural polypeptides of five rabies virus strains (serotype 1) and one serotype IV, demonstrates difference in molecular weight of the envelope polypeptides M1 and G of all strains. There is little difference between the structural polypeptides N, M2 and probably L. Some purified strains have been treated by trypsine to localize the position of polypeptides. There was no difference between the four major polypeptides of complete and defective virus. Pasteur strain cultivated on different cells shows very little difference in molecular weight of the four major polypeptides.
