This peptide is widely used in immunological research, particularly in studies focusing on T-cell responses and viral infections. It serves as a specific antigen to stimulate and analyze CD8+ T-cell activity in murine models, especially in the context of Lymphocytic Choriomeningitis Virus (LCMV) infection. Researchers utilize it to investigate immune memory, vaccine efficacy, and T-cell receptor interactions. Additionally, it is employed in cancer immunotherapy studies to explore the potential of T-cell-mediated tumor regression. Its application extends to understanding immune evasion mechanisms and developing targeted immunotherapies.
