In this paper, we describe a rapid flow cytometry method to identify antimicrobial peptides that are internalized into bacterial cells and differentiate them from those that are membrane active. The method was applied to fluorescently labeled Bac7(1-35) and polymyxin B, whose mechanisms of action are, respectively, based on cell penetration ... More
