Physicochemical Solubility & Storage Parameters
| Product Code | Appearance | Long-term Storage | Short-term Storage | Solution Stability | Solid Powder Stability |
| PEP-CEF6-01 | White to off-white powder | Store at -20℃, dry, sealed, protected from light (1 Met, guard against oxidation; inert gas preferred) | Short-term at 2-8℃, sealed and dry (days to 2 weeks) | Hydrophobic epitope peptide (many L/P/F/V residues): first dissolve in a small volume of DMSO, then dilute; contains Met - avoid oxidants and repeated freeze-thaw, prepare fresh; contains D/K polar residues, sonication in water can be attempted | powder stable at -20℃ when dry and sealed; Met is oxidation-prone - minimize air exposure, keep dry |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Receptors |
| PEP-CEF6-01 | CEF pool member #6: the 9-mer LPFDKTTVM spanning residues 418-426 of the influenza A virus (H1N1) nucleoprotein NP, an HLA-B*07:02-restricted CD8+ CTL epitope; a positive control for ELISPOT/T-cell monitoring. | CEF6 is member #6 of the CEF (CMV/EBV/Influenza) mixed peptide pool, corresponding to residues 418-426 (LPFDKTTVM) of the nucleoprotein (NP) of influenza A virus (H1N1); an HLA-B*07:02-restricted CD8+ T-cell epitope (eluted from HLA-B*0702 in mass-spectrometry studies). The CEF pool is a routine positive control in ELISPOT/ICS and other T-cell assays. This product is the single pool member, used for: monitoring influenza-specific CD8+ T-cell responses, immune monitoring in HLA-B7-associated populations, reconstitution of the CEF pool, epitope-specific tetramer preparation and vaccine research. Contains 1 Met: protect from oxidation during storage and reconstitution. | Viral immunology, influenza virus, cellular immune monitoring, ELISPOT positive control, CEF pool, HLA-B7 epitopes | HLA-B*07:02 (MHC class I); influenza NP-specific CD8+ T cells |
