摘要
Many clade C isolates of HIV-1 do not react with monoclonal antibody (MAb) 2G12, a broad-ranging human neutralizing MAb that recognizes high mannose carbohydrate groups attached to glycoprotein gp120. We reintroduced a partial and complete 2G12 epitope into a clade C background, HIV-1(CN54), and examined the antibody reactivity of the resulting recombinant molecules. Two glycosylation sites recovered 2G12 binding completely, but some binding was evident after the reintroduction of a single glycosylation site at Asn295.
