Abstract

It has shown that the human immunodeficiency virus type 1 (HIV-1) Nef protein has the high antigenicity in HIV-1 seropositive individuals. We newly obtained seven monoclonal antibodies (mAbs). To identify the antigenic determinants of HIV-1 Nef protein against murine, epitope mapping of the mAbs was performed by enzyme-linked immunosorbent assay (ELISA) by using several recombinant truncated Nef fusion proteins, that were expressed in Esherichia coli, and synthetic peptides. The results showed that mAbs A6, A7, F2, F3, F4, F8 and E5 recognized epitopes on Nef protein located at amino acid residues 18-26, 28-45, 115-137, 128-137, 115-126, 128-137, and 170-181, respectively.
