- W2083334880 abstract "Gamma and kappa chain cDNAs from four mouse monoclonal antibodies (mAbs) which bind three different sites on the core antigen (p24) of HIV-1 have been cloned and their V-region sequences determined. These mAbs are part of a larger group of seven anti-p24 mAbs analyzed in simultaneous competition assays with HIV-1 lysate as antigen and in protein blotting experiments using 10 carboxy-terminal truncations of a p24 fusion protein. One mAb, BB128, recognizes the p24 loop sequence EAAEWDRVHP and enhances the binding of two other mAbs (BI1777 and BI1279) when tested pairwise in simultaneous competition assays. The two monoclonals enhanced by BB128 recognize different antigenic sites on p24, with BI1777 binding to carboxy-terminal sequences and BI1279 to amino-terminal residues. In the pairwise assays, mAb BI1279 also acts as enhancing antibody for BI1777, as does mAb BB328, which recognizes residues in the central region of p24. Since aggregated p24 monomers form the HIV-1 capsid, p24 is a multivalent antigen in HIV-1 lysate. It seems likely, therefore, that synergistic binding of mAb pairs to p24 is effected by bivalent binding of the enhancing mAb stabilizing a conformation favorable for bivalent binding of the enhanced mAb." @default.
