Pulse-chase experiments, investigations on the effects of rifampicin and direct analysis of precipitin lines by gel electrophoresis allowed the identification of two major precipitin lines in terms of the polypeptides specific for the infected cell. One of these was non-structural. A small proportion of the other antigen was incorporated into sedimentable structures during a chase; this was prevented by rifampicin. Evidence suggesting that three virus-specified polypeptides are formed by cleavage of larger precursors is also presented and discussed. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-19-1-65
