Application: CEF2 is a synthetic HLA-A*0201-restricted epitope derived from influenza virus RNA polymerase subunit PA, spanning amino acids 46–54. This well-defined viral peptide functions as a CD8⁺ T-cell antigen and is widely used in viral immunology research. CEF2 supports studies of antigen presentation, cytotoxic T lymphocyte activation, immune monitoring, epitope mapping, and vaccine development related to influenza infection. Frequently used in cellular immune assays, this peptide provides a valuable tool for investigating adaptive immune recognition of conserved influenza-derived epitopes and evaluating influenza-specific T-cell responses in HLA-matched research systems.
