Mason-Pfizer monkey virus immature capsids selected from the
cytoplasm of baculovirus-infected cells were imaged by scanning transmission electron microscopy. The masses of individual selected Gag
particles were measured, and the average mass corresponded to 1,900 to
2,100 Gag polyproteins per particle. A large variation in Gag particle
mass was observed within each population measured.
