FIGURE 5.
Eater-Fc does not bind to live and formaldehyde-inactivated Gram-negative bacteria. Shown is flow cytometry analysis of binding by 200 μm biotinylated Eater-Fc fusion protein (open black curve) when compared with secondary reagent only (gray filled curve) or unstained microbes (open gray curve). Eater-Fc did not bind to live or formaldehyde-inactivated Proteobacteria (left and middle panels). Right panels, control binding to heat- or ethanol-inactivated Proteobacteria. EtOH-I., ethanol-inactivated. These experiments were repeated two times with similar results.
