Atomic force microscopy of cholera toxin B-oligomers bound to bilayers of biologically relevant lipids.

Cholera toxin B-oligomer was imaged by atomic force microscopy (AFM) on biologically relevant model membranes, such as 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine and egg yolk phosphatidylcholine at room temperature in solution at a resolution in the range of 1 to 2 nm. In addition, two-dimensional arrays were grown directly on these model… CONTINUE READING
