Effect of NaCl concentration and the Volta-phase plate on the tomographic data. a A slice through a 3D tomogram of HRPV-6 in 1.5 M NaCl buffer collected without Volta-phase plate. b A slice through a 3D tomogram of HRPV-6 in 1.5 M NaCl buffer collected with Volta-phase plate (left), and the corresponding cross section of cylindrically average spike and density distribution (right). c A slice through a 3D tomogram of HRPV-6 in 0.25 M NaCl buffer collected with Volta-phase plate (left), and the corresponding cross section of cylindrically average spike and density distribution (right). d Averaged radial density distributions of HRPV-6 in low (0.25 M NaCl) and high salt (1.5 M NaCl) are compared. The radial density distribution for the spike is similar at low- and high-salt concentration. The scale bar corresponds to 100 nm. Source data are provided as a Source Data file
