FIG. 4.

H-111 inhibition of the binding of HCV-LPs to MOLT-4 cells. SYTO-labeled HCV-LPs were preincubated with increasing amounts of H-111 or control HMAb R04 and were then incubated with MOLT-4 cells. Cell-bound HCV-LPs were analyzed by flow cytometry. The y axis shows mean fluorescence intensity (MFI), and the x axis shows the antibody (Ab) concentration. Filled diamonds, H-111; open diamonds, control antibody.
