Localization of A33R, A34R, and A36R in vaccinia virus-infected HeLa cells. WR-infected cells were labeled with antibodies against A33R, A34R, or A36R as indicated on the left and with an antiactin antibody. Inserts in the merged images clearly show that all three IEV proteins (red) are localized to viral particles at the tips of actin tails (green). Bar, 10 μm.
