[Ile161]MAGE – A2 (157-166)

<p>[Ile161]MAGE-A2 (157-166) is a modified synthetic peptide analog derived from the melanoma-associated antigen A2 (MAGE-A2). Designed with an isoleucine substitution at position 161, this high-purity epitope enhances stability and HLA binding affinity. It is essential for cancer immunotherapy research, specifically in studying T-cell responses, vaccine development, and targeted immunological assays against MAGE-A2…

1.MECHANISM OF ACTION

This peptide functions as an optimized HLA class I-restricted epitope, preferentially presented by HLA-A*02:01 molecules. The Ile161 substitution strengthens peptide-MHC complex stability, leading to more efficient activation of cytotoxic T-lymphocytes (CTLs). These activated CTLs specifically recognize and lyse tumor cells expressing the MAGE-A2 antigen, providing a targeted model for investigating adaptive antitumor immunity.

2.PRODUCT INDICATIONS

This product is indicated for research applications in oncology and immunology, including in vitro T-cell stimulation, immune monitoring assays, cancer vaccine design, and preclinical evaluation of adoptive cell therapies. It is also used for epitope optimization studies and as a reference standard in diagnostic development for cancers such as melanoma, lung, and head and neck carcinomas.

3.CLINICAL EFFICACY OF PRODUCT

Although intended for research, preclinical data indicate that modified MAGE-A2 epitopes like [Ile161]MAGE-A2 (157-166) can elicit stronger and more persistent CTL responses compared to wild-type sequences. This enhanced immunogenicity supports its role in improving the efficacy of peptide-based vaccines and T-cell therapies currently under investigation in clinical trials for solid tumors.
