Figure 3. Penetration of NKLP27 into the target bacterial cells.

Vibrio anguillarum was incubated with FAM-labeled NKLP27 (D and E) or the control peptide P86P15 (A and B) for 0.5 h. After quenching extracellular fluorescence, the cells were observed under a microscope with (B and E) or without (A and D) fluorescence. C, merged image of A and B; F, merged image of D and E.
