Figure 4. Neutralizing activity of anti-gp140 antibodies in TZM-bl assay.
Numbers indicate antibody IgG concentrations in µg/ml to reach the IC50 in the in vitro TZM-bl neutralization assay. > indicates that the IC50 for a given virus was not reached at the concentration tested. 9-1487 antibody was not tested for viral neutralization. *10-188 and 10-380 are clonally related antibodies. ND, not determined. MuLV, Murine leukemia virus, is the negative control.
