Physicochemical Solubility & Storage Parameters
| Product Code | Appearance | Long-term Storage | Short-term Storage | Solution Stability | Solid Powder Stability |
| PEP-HBVC63-01 | White to off-white powder | -20 °C, dry, protected from light, sealed storage; nitrogen flush preferred. | 2–8 °C short-term; aliquot working solutions and store frozen at -20 °C. | Contains Met (position 4), which oxidizes readily, and Trp (position 9), which is light-sensitive and prone to oxidation/degradation; strongly hydrophobic (enriched in L/A/V/T/W) with poor water solubility, requiring DMSO-assisted dissolution with sonication. Prepare fresh, protect from light and flush with inert gas. | Relatively stable as powder under dry, sealed, light-protected, nitrogen-flushed conditions. |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Receptors |
| PEP-HBVC63-01 | 9-mer CTL epitope from hepatitis B virus core protein (HBcAg) residues 63–71, for HBV-specific CD8+ T-cell immunity studies. | The 9-mer from HBV core antigen (HBcAg/Capsid protein) residues 63–71 is an epitope recognized by HBV-specific CD8+ cytotoxic T lymphocytes (CTLs). Used for immune-status assessment in chronic hepatitis B, HBV vaccine development, therapeutic vaccines, T-cell response monitoring (ELISpot/tetramer) and studies of viral clearance mechanisms. The commercial sequence GELMTLATW differs from the UniProt P03147 isolate GDLMTLATW by a D/E genotype polymorphism at position 64. | Hepatitis B; HBcAg; CTL epitope; therapeutic vaccine; viral immunity | MHC class I (CD8+ T-cell epitope) |
