Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Pathways |
| PEP-FLM1-01 | A 12-mer peptide spanning residues 61-72 of influenza A virus matrix protein M1; induces CD4+ T-cell responses and is used for influenza-specific T-cell assays and vaccine development. | Influenza Matrix Protein (61-72) is a 12-amino-acid peptide (GFVFTLTVPSER) derived from residues 61-72 of the influenza A virus matrix protein M1. The upstream 58-66 segment GILGFVFTL is the well-known HLA-A*02:01-restricted CD8+ CTL epitope, whereas the 61-72 fragment serves as a specific epitope that can elicit CD4+ T-cell responses. It is widely used to detect post-influenza T-cell immunity, to establish epitope-specific T-cell lines, in ELISpot and intracellular cytokine staining assays, and in influenza vaccine and immunogen-design studies. | Influenza virology,vaccine development,T-cell epitope mapping,infection immunity | Influenza A virus M1 matrix protein; MHC-II-restricted CD4+ T-cell epitope |
