| IRGRILHDGAYSLTLQGLGIH TFA salt (rat HER2/neu class II MHC multi-epitope peptide; CAS 1443436-79-0) | IRGRILHDGAYSLTLQGLGIH TFA, rat HER2/neu class II peptide TFA salt, class II HER2-DC1 vaccine peptide, PEP-HER2IITF-01 | T-cell epitope, MHC class II, CD4 T cell, cancer vaccine, HER2 immunotherapy, dendritic cell vaccine, TFA salt hygroscopic | IRGRILHDGAYSLTLQGLGIH (H-Ile-Arg-Gly-Arg-Ile-Leu-His-Asp-Gly-Ala-Tyr-Ser-Leu-Thr-Leu-Gln-Gly-Leu-Gly-Ile-His-OH, linear 21-mer, free N-terminal amino / free C-terminal carboxyl, supplied as the trifluoroacetate (TFA) salt) | C102H168N32O28 | 2289.27 | 2290.66 | TFA salt (trifluoroacetate; more hygroscopic than the free-acid peptide) | 21 |
Physicochemical Solubility & Storage Parameters
| Product Code | Appearance | Long-term Storage | Short-term Storage | Solution Stability | Solid Powder Stability |
| PEP-HER2IITF-01 | white to off-white (MCE, purity ≥95% HPLC; trifluoroacetate/TFA salt, hygroscopic) | Store frozen below -20°C, protected from light, dry and tightly sealed (with desiccant); the TFA salt is hygroscopic-keep moisture out | Store at 4°C sealed, dry and light-protected, use within 2-4 weeks (TFA salt absorbs moisture-recap promptly and keep with desiccant); after reconstitution aliquot and store at -20°C, avoid repeated freeze-thaw | Moderately soluble in water (21-mer, ~38% hydrophobic); contains 1 Tyr (light-sensitive), no Cys/Met; reconstitute in sterile water or PBS with sonication if needed; protect from light and aliquot for storage | powder stable long-term at -20°C when dry, light-protected and sealed; keep moisture- and light-protected. This product is the TFA salt and is relatively hygroscopic-weigh quickly after opening, immediately reseal with desiccant and keep light-protected; if equilibrating to room temperature, do so in a desiccator to avoid moisture uptake. |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Pathways |
| PEP-HER2IITF-01 | A multi-epitope MHC class II peptide derived from rat HER2/neu (TFA salt), used in HER2-DC1 dendritic-cell cancer-vaccine and CD4 T-cell studies. | IRGRILHDGAYSLTLQGLGIH is a multi-epitope MHC class II (CD4) peptide derived from the rat HER2/neu oncoprotein. It is loaded onto dendritic cells (DC1) to generate HER2 vaccines, eliciting CD4 T-cell responses in HER2-positive mammary carcinoma models and synergizing with sequential anti-PD-1 therapy to improve survival. It is used in tumor immunotherapy and epitope-vaccine design. | Tumor immunology, cancer vaccine, dendritic cell vaccine, MHC class II epitope, HER2-targeted therapy, immunotherapy | MHC class II (CD4 T-cell recognition; rat HER2/neu) |
