FIG 3.

EBOV GP begins to mediate cytoplasmic entry after a 30-min lag whether on a filamentous VLP or a spherical retroviral pseudovirion. VLPs (triangles, dashed line) or HIV pseudovirions (x, solid line) bearing EBOV GP were bound to BSC-1 cells at 4°C, warmed to 37°C, and analyzed for cytoplasmic entry as described for Fig. 1. Each data point is the average from four samples (from two experiments performed in duplicate). Error bars indicate SD. None of the data points are statistically different at P values of <0.05.
