Purification of engineered magnetosomes (∆F-BMP-FA). a Magnetic rack containing purified ∆F-BMP-FA (arrow). b Protein concentration in supernatant following various numbers of wash cycles. Protein concentration fell below 0.1 following seven wash cycles, and no further protein was dropped as number of wash cycles increased. c Electron micrograph of purified ∆F-BMP-FA after seven wash cycles. Photo background reveals no stain; i.e., ∆F-BMP-FA was well purified. d Schematic diagram of BMP-A-Ab complex
