| PEP-NP001 | Influenza nucleoprotein NP (118-126) nonapeptide, canonical MHC-I restricted CTL epitope for viral immunity, T cell response and vaccine screening research | Nucleoprotein (118-126) is a conserved immunodominant epitope derived from influenza A nucleoprotein. It efficiently binds MHC class I molecules and specifically activates CD8⁺ cytotoxic T lymphocytes (CTL). The sequence is highly conserved with low mutation rate among various influenza A strains. It is widely used for cellular immune response detection after viral infection, T cell proliferation/killing assays, antigen substrate for ELISA/ELISPOT, in vitro screening of broad-spectrum antiviral epitope vaccines, applicable to virology, immunodiagnosis and anti-infective vaccine development research | Viral immunology, influenza immunodominant epitope, MHC-I antigen presentation, CTL activation, immunodiagnosis, antiviral vaccine screening | MHC class I molecules, CD8⁺ T cell receptor, NP-specific antibody |
