Specificity of biarsenical dye labeling. Vero cells were infected with Q94-TC or WT SINV at a multiplicity of 0.5 IC/cell, cultured for 7 h at 37°C, and labeled with ReAsH as described in Materials and Methods. Cells were then fixed, permeabilized, and stained with antibody against the capsid protein. Images are single internal z sections and are representative of two independent experiments. Bar, 10 μM.
