Figure 2From: Inhibition of HIV Env binding to cellular receptors by monoclonal antibody 2G12 as probed by Fc-tagged gp120Binding of Fc-gp120 chimeras to cellular CD4. Inhibition of binding of Fc-gp120 chimeras to CEM-CD4 cells by (A) sCD4, (B) Fab b12 or (C) Fab 2G12. Inhibition of binding was assessed by FACS analysis and is expressed as % binding inhibition. Results are means of triplicate determinations.Back to article page
