FIG. 2.

Proteins p35 and p15 reside at the core shell. Thawed cryosections of BA71V-infected cells fixed at 20 hpi were incubated with anti-p35 (A) or anti-p15 (B) antibodies followed by protein A-gold (10-nm diameter). Within the virus factory, the pp62 labeling can be observed close to precursor viral membranes (arrows), at the immature core region of assembling virions (small arrowheads), and at the core shell (large arrowheads) surrounding the electron-dense nucleoid of mature particles. The core shell appears delimited in a virus particle in panel B. Bars, 100 nm.
