MeV L, P, and HSP90 colocalize within virus-induced inclusion bodies. (A) Vero/hSLAM cells were infected at an MOI of 0.1 with a recombinant MeV expressing a Flag-tagged L protein or not infected. At 24 hpi, cells were fixed, the L or P (left side) and P or HSP90 (middle) proteins were immunolabeled, and images were overlaid for colocalization (right side). White arrows indicate noninfected cells. White bars represent 10 μm.
