G280-9 acetate (156761-76-1 free base)

G280-9 acetate is an HLA-A2-restricted peptide epitope derived from the melanoma-associated antigen gp100. Despite its high T-cell recognition sensitivity at low concentrations, its overall immunogenicity is limited by a low binding affinity for HLA-A2. This peptide is utilized in immunological research for studying T-cell responses and evaluating vaccine candidates in both in vitro and in vivo experimental models.
