This negative stained transmission electron microscopic (TEM) image showed recreated 1918 influenza virions that were collected from the supernatant of a 1918-infected Madin-Darby Canine Kidney (MDCK) cell culture, 18 hours after infection. In order to sequester these virions, the MDCK cells were spun down, in a process known as centrifugation, and the 1918 virus present in the fluid was immediately fixed for negative staining.
