A. fumigatus can transport iron from transferrin across a dialysis membrane. A. fumigatus was inoculated into MEM in which a dialysis bag containing holotransferrin (25 μM) was suspended. A. fumigatus was incubated for 48 h, and then transferrin was withdrawn from the dialysis bag and analyzed by urea-PAGE (lane +). An uninoculated control flask containing MEM plus transferrin in a dialysis bag also was examined (lane −). Pure holotransferrin (Fe2-Tf) and apotransferrin (Apo-Tf) standards also were run.
