Cells infected with the indicated proviruses were double immunogold labeled for Gag and DDX6. In two independent labeling experiments, the following parameters were quantified: the total length of membrane examined, the total number of independent DDX6 labeling events within 100 nm of the membrane, the total number of independent targeted, early, and late Gag clusters, and the total number of Gag clusters that were associated with DDX6 classified by stage of assembly (i.e., targeted Gag or Gag at early or late assembly sites). Fold colocalization is defined as the number of WT Gag clusters colocalized with DDX6 for each stage of assembly, normalized to Gag-DDX6 colocalization in the GagΔp2-NC-p1-p6 negative control (indicated by parentheses). Fold colocalization (bold) was calculated for each experiment. The fold colocalization averaged from the two experiments is shown and is also graphed with SD in Fig. 5.
