Fig. 2From: 3D reconstruction of biological structures: automated procedures for alignment and reconstruction of multiple tilt series in electron tomographyTEM micrograph of a plastic section containing Mimivirus virions infecting a cell culture at 4h post infection. The sample is at zero tilt; 5-nm gold particles (G) are used as fiducial markers for aligning the tilt series. The enclosed area corresponds to the capsid envelope portion displayed in Fig. 3 Back to article page
