Deposition of the Membrane Attack Complement Complex (MAC) on Escherichia Coli strain BL21 viewed by Atomic Force Microscopy (AFM). Bacteria are incubated with normal human serum (as a source for complement) for 10 min at 37°C and subsequently analysed in the AFM. Pseudo-colors display the sensor hight. The MAC forms a ring-shaped structure of multiple C9 molecules embedded in the outer membrane of the bacteria.
