Competition between ferri-Tf or ferri-Lf and apo-Tf or apo-Lf. H. pylori strain 26695m (A to D) or N. gonorrhoeae (E and F) was incubated with FITC-labeled protein in the presence or absence of excess unlabeled protein. The fluorescence of bacteria was measured by flow cytometry. (A) FITC-ferri-Lf with or without a 50-fold excess of unlabeled apo-Lf. (B) FITC-apo-Lf with or without a 50-fold excess of unlabeled ferri-Lf. (C) FITC-ferri-Tf with or without a 50-fold excess of unlabeled apo-Tf. (D) FITC-apo-Tf with or without a 50-fold excess of unlabeled ferri-Tf. (E) N. gonorrhoeae incubated with FITC-ferri-Lf with or without a 50-fold excess of unlabeled apo-Lf. (F) N. gonorrhoeae incubated with FITC-apo-Lf with or without a 50-fold excess of unlabeled ferri-Lf. hTf, human Tf; bLf, bovine Lf.
