| PEP-CEF14RTA-01 | EBV Rta 28-37 (DYCNVLNKEF), HLA-A*24:02-restricted CD8 epitope; a member of the CEF peptide pool. | CEF14 is the HLA-A*24:02-restricted CD8+ T-cell epitope spanning residues 28-37 of the EBV immediate-early lytic-cycle transactivator Rta (encoded by BRLF1). As a component of the CEF peptide pool (pooled CMV/EBV/Influenza CD8 epitopes), it is used to detect EBV-specific CD8+ T-cell responses (ELISpot, intracellular cytokine staining), monitor virus-specific cellular immunity and study EBV-associated disease immunology. | EBV immunology,CD8+ CTL epitopes,CEF peptide pool,ELISpot / T-cell monitoring,Virus-specific cellular immunity | Presented by HLA-A*24:02 (MHC class I); recognized by EBV-specific CD8+ T-cell receptors |
