Physicochemical Solubility & Storage Parameters
| Product Code | Appearance | Long-term Storage | Short-term Storage | Solution Stability | Solid Powder Stability |
| PEP-FLUNP147-01 | White to off-white powder | -20 °C or below (recommended -20 °C ±5 °C), protected from light, dry and sealed; aliquot to avoid repeated freeze-thaw cycles | 2–8 °C for short-term transport/storage (days to weeks) | Contains Tyr/Trp-like aromatic residues; protect from light in solution. Prepare fresh before use; store working aliquots at -20 °C and avoid repeated freeze-thaw. A somewhat hydrophobic epitope with limited solubility in pure water; first dissolve in a small volume of DMSO, then dilute with water/buffer. | Stable as powder; can be stored long-term under desiccation; degrades upon moisture absorption. |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Receptors |
| PEP-FLUNP147-01 | H-2Kd-restricted 9-mer CTL epitope from influenza nucleoprotein, for murine CD8+ T-cell response, vaccine and infection-immunity studies. | Influenza NP (147-155) is the classic immunodominant epitope presented by the murine MHC class I molecule H-2Kd, derived from residues 147–155 of the nucleoprotein (NP) of influenza A/PR/8/34 (PR8) virus. It is specifically recognized by CD8+ cytotoxic T lymphocytes (CTLs) in PR8-infected mice, which then kill infected cells. It is one of the most widely used peptide–MHC tetramer antigen peptides in mouse influenza models, broadly applied to influenza vaccine development, cross-protective immunity, CTL response quantification (ELISPOT/ICC) and memory T-cell studies. | Viral immunology; influenza vaccines; CTL/CD8+ T-cell immunity; MHC-I antigen presentation; infection and immune memory | Murine H-2Kd (MHC class I); CD8+ T-cell TCR |
