  • The transmembrane glycoprotein (gp32) of the simian immunodeficiency virus (SIV) contains a highly antigenic region that includes amino acid residues 606-628. A synthetic peptide representing this region was highly immunoreactive with sera from SIV-infected primates in a site-directed enzyme-linked immunosorbent assay (ELISA). This reactivity extended across four primate species from three genera and identified infection with at least two distinct isolates of SIV. This site-directed ELISA represents a simple, accessible method with broad specificity for screening large numbers of primates for antibodies against SIV.
