title: In vitro radiolabeling procedure which labels the proteins of Newcastle disease virions with carbon-14.
abstract: A convenient and gentle procedure was used for in vitro radioisotopic labeling the proteins of Newcastle disease virus. This method, which utilizes [14C]formaldehyde and sodium borohydride, labels all the proteins of purified Newcastle disease virus. Virions labeled in this manner retained biological and biopysical integrity
