In vitro iron co-precipitation assay. (a) Size distribution of magnetite particles obtained with different proteins at a concentration of 10 µg ml−1 or in a protein-free experiment. The red line refers to the maximum size achieved by 90% of the particle population in the control experiment. (b) Magnetic particles prepared in vitro by magnetite precipitation with MC K313 and MC K170. Scale bars represent 200 nm and a histogram analysis is shown for each sample. |
