FIG. 5.
Binding of the recombinant Mam22 to alkaline-treated magnetosomes. (A) Transmission electron micrograph of alkaline-treated magnetosomes incubated with recombinant Mam22. The 5-nm immunogold particles specific for Mam22 were observed around the magnetosomal matrix. (B) Transmission electron micrograph of alkaline-treated magnetosomes that were not incubated with recombinant Mam22 as a control. No gold particles were found around the magnetosomes.
