Fig. 2From: Internalization of a Bacillus anthracis Protective Antigen-c-Myc Fusion Protein Mediated by Cell Surface Anti-c-Myc AntibodiesThe 9E10 mouse hybridoma cell line presents IgG on the cell surface. The relative amount of IgG on the cell surface was determined both by FACS and by immunoassay. FITC-conjugated goat anti-mouse IgG bound cells were analyzed by FACS and the results given as the mean fluorescence of the sorted cells (bar graph). For the immunoassay, the HRP-conjugated goat anti-mouse IgG bound cells were resuspended in ABTS and citrate buffer and the absorbance measured at 405 nm (line graph).Back to article page
