| PEP-HAPEP-01 | White to off-white powder (TFA salt form) | Store at -20°C or below, light-protected, dry and sealed (3 Tyr); TFA salt is hygroscopic - keep in a desiccator after opening; reconstituted aliquots ~1 year at -80°C | Store at 4°C, light-protected, sealed and dry, use within 2-4 weeks; after reconstitution aliquot and freeze at -20°C, light-protected | Contains 3 Tyr (light-sensitive - protect during handling and storage) and 2 Asp (net charge ~-2); ~40% hydrophobic residues, moderate water solubility: pre-dissolve in a small volume of DMSO or PBS (pH 7-8), then vortex/sonicate to complete dissolution. No Cys (this is YPYDVPDYA, thiol-free) or Met. Aliquot at -20°C; avoid repeated freeze-thaw | powder stable 2-3 years at -20°C when dry and sealed; protect from light and moisture (TFA salt); aliquot promptly after opening and keep in a desiccator |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Receptors |
| PEP-HAPEP-01 | Influenza hemagglutinin HA tag peptide YPYDVPDYA (9-mer, CAS 92000-76-5) for detection and affinity-purification elution of HA-tagged fusion proteins; TFA salt form. | The HA tag peptide corresponds to residues 98-106 (YPYDVPDYA) of influenza A virus hemagglutinin (HA, HA1 subunit), the classic immunodominant epitope recognized by mAbs 12CA5 and 3F10, and one of the most widely used protein epitope tags. As a fusion tag it is used for Western blot, immunoprecipitation/Co-IP and immunofluorescence detection of recombinant proteins, and for affinity purification on anti-HA resins with gentle competitive elution using the free HA peptide (1 mg/mL TBS). This product is the 9-mer YPYDVPDYA (CAS 92000-76-5); for conjugation to KLH/BSA carrier proteins for antibody production, use the N-terminal Cys 10-mer CYPYDVPDYA (CAS 92000-72-1, sold separately). Contains 3 Tyr - protect from light. | Immunology,protein tags,fusion protein identification,protein purification,vaccine research | Recognized by anti-HA mAbs (12CA5, 3F10); HA-tagged fusion proteins |
