Morphology of BKPyV produced in 293TT cells. Virus was purified from cells by CsCl gradient centrifugation. Mature virus particles were applied to grids as described in the text. Viral particles were visualized by negative staining at a magnification of 180,000X. Archetype virions from 293TT cells are shown in the left column, rearranged virions from the same cells in the middle column, and rearranged virions purified from Vero cells in the right column. Scale bar = 50 nm. The particles shown are representative of three independent purifications.
