Precursor Protein for Newcastle Disease Virus [PDF]

open access: yesJournal of Virology, 1973
The course of viral protein synthesis during infection of chicken embryo fibroblasts with Newcastle disease virus (NDV) L. Kansas has been followed by using sodium dodecyl sulfate polyacrylamide gel electrophoresis. Of the three major virion polypeptide molecular weight classes, I (78,400 daltons), II (53,500 daltons), and III (37,600 daltons), only II,
