Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Pathways |
| PEP-TETX830-01 | Tetanus toxin 830-843 (QYIKANSKFIGITE), pan-HLA-DR universal Th helper epitope for vaccine design. | A universal pan-HLA-DR T-helper (Th, classic 'p2') epitope derived from the C-fragment of the tetanus toxin (TeNT) heavy chain (residues 830-843). Widely used as a 'bystander' helper epitope in peptide vaccines to boost the immunogenicity of co-delivered B-cell or CD8+ CTL epitopes, and in human T-cell recall assays and vaccine-adjuvant activity assessment. | Immunology,Vaccine development,T-helper epitopes,Tumor/infection immunology | HLA-DR (multiple DR alleles, pan-DR restricted); CD4+ helper T cells |
