gp100 (476-485)

<p>gp100 (476-485) is a high-purity synthetic peptide representing an HLA-A*0201-restricted cytotoxic T lymphocyte (CTL) epitope derived from the human melanoma-associated antigen gp100/pMel 17. This 10-amino acid peptide (ILTPPSSLRL) serves as an immunogenic epitope that can be presented by MHC class I molecules to activate antigen-specific CD8+ T cells. Manufactured under stringent quality controls with HPLC-verif…

1.MECHANISM OF ACTION

gp100 (476-485) functions as a tumor-associated antigen peptide that binds to HLA-A0201 molecules on antigen-presenting cells (APCs), forming peptide-MHC complexes that are recognized by T cell receptors (TCRs) on CD8+ T cells. This specific interaction triggers T cell activation, proliferation, and differentiation into cytotoxic T lymphocytes (CTLs). The activated CTLs then recognize and eliminate tumor cells expressing the gp100 antigen through perforin/granzyme-mediated cytotoxicity and cytokine release (such as IFN-γ). The peptide's immunogenicity is characterized by its ability to induce robust T cell responses in HLA-A0201-positive individuals, making it valuable for both in vitro and in vivo immunological studies.
