Site-Specific Chemoenzymatic Labeling of Aerolysin Enables the Identification of New Aerolysin Receptors
Figure 5
Aerolysin variants, fluorescently labeled, bind to the cell surface of HeLa cells. Images were acquired by confocal fluorescence microscopy. A Single labeled aerolysin versions. For comparable signal intensity, different aerolysin concentrations were required as indicated. B Double-labeled aerolysin and unlabeled aerolysin control.
