HIV gp120 (318-327)

This synthetic peptide corresponds to the conserved C-terminal region (rgpgrafvti) of the HIV-1 IIIB gp120 V3 loop. While lacking canonical A2 anchors for specific CTL recognition, it exhibits mixed HLA-A2 binding properties. It is utilized in immunological research for studying T-cell responses, epitope mapping, and vaccine design in both in vitro and ex vivo assays.
