FIG. 4.

Characterization of MV binding to CEF with inhibitors. CEF or CHO.CD46 cells or purified MV Hallé strain was preincubated with different inhibitors prior to the virus binding assay. Results were expressed as percentages of inhibition of MV binding ability. (A) Inhibitory ability of recombinant soluble CD46 (black columns) or hemagglutinin (stippled columns). (B) Inhibitory ability of monoclonal anti-MV hemagglutinin antibodies: Cl55 (triangles), 48Cl6 (circles), and 19H40 (squares). (C) Inhibitory ability of anti-H polyclonal antibodies: monkey antiserum Bms 94 (crosses), guinea pig antiserum Houx (diamonds), and rabbit antiserum Harry (arrowheads).
