Wide field IFA time course of invasion using anti-PfActin/PfRON4. IFA scale bar = 2.0 μm. The distribution of actin within the merozoite was concentrated at the parasite apex, with diffuse labeling elsewhere in the cytoplasm (Actin early). Actin fluorescence could be detected, concentrated at the tight junction (Actin mid). In the latter stages of invasion, the concentration of actin labeling was at the rear of the invaded merozoite (Actin late).
