We have defined continuous native epitopes of HIV proteins by using a systematic epitope-scanning technology. We have demonstrated that there is a highly immunoreactive continuous native epitope region in the transmembrane protein gp41 of HIV-1 that is immunoreactive with all studied HIV-1 antibody-positive sera. The corresponding region in HIV-2 gp34 behaves similarly. There is a clear difference, however, between HIV type 1 and type 2 transmembrane proteins in the number of highly immunoreactive regions, when presented properly as synthetic antigens in solid-phase EIA, can provide tests unusually suitable for early and reliable diagnosis of HIV-1 and HIV-2 infections and for type-specific distinction of the two types of HIV infections.
