Two separate preparations of virus gave similar results. These three N-terminal amino acids were recovered in amounts consistent with about 60 molecules of each per virus particle, or 1 mol of each per mol of virus protein., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-21-3-443
