Application: CEF20 is an HLA-A*0201-restricted CD8⁺ T-cell epitope derived from cytomegalovirus tegument protein pp65, spanning residues 495–503. This immunodominant viral peptide is widely used in CMV immunology research to monitor antiviral T-cell responses in infection, transplantation, and vaccine studies. CEF20 is commonly applied in tetramer staining, ELISPOT, functional cytotoxicity testing, epitope mapping, and immune monitoring assays. It provides a reliable peptide tool for evaluating CMV-specific cellular immune competence, antigen presentation, cytotoxic T lymphocyte activity, and adaptive antiviral immunity in HLA-matched research systems.
