Negative staining and electron tomographic analysis of a suspected feature. Figure 3A represents a micrograph of a negatively stained feature that, based on its size and general aspect, can be mistaken for a virion of a paramyxovirus. Figure 3B is a central digital section of 44 nm thick along the Z-axis of the tomogram of the feature shown in Figure 3A. Bar A, B: 100 nm.
