CryoEM of EBOV. (A) Low-magnification cryoEM images of purified EBOV. Protein density is black. Filamentous particles of varying lengths, spherical particles, and other irregularly shaped particles are observed. (B) CryoEM image of a filamentous EBOV virion. White arrow, EBOV virion with an NC. Black arrow, a thin particle without an internalized NC. (C) Histograms of virion length (Left) and diameter (Right) for filamentous EBOV virions containing an NC. (D) Corresponding histograms for MARV. More details in Fig. S1 and SI Materials and Methods.
