| Peptide 78 | Peptide 78; TMRKPRSGNPDVAN; CAS 132116-62-2 (registered 14-mer; trade name conflated with ENA-78/CXCL5 - check molecular identity) | 14-mer,chemokine-related,neutrophil,inflammation,tool peptide | H-Thr-Met-Arg-Lys-Pro-Arg-Ser-Gly-Asn-Pro-Asp-Val-Ala-Asn-OH (CAS 132116-62-2 registers this 14-mer; trade name 'Peptide 78/ENA-78(CXCL5)' is vendor marketing - NOT the full-length 78-aa chemokine (~8.3 kDa); contains 1 Met - anti-oxidation required) | C62H107N23O21S | 1541.77 | 1542.73 | Supplied as powder; acetate/TFA salt not specified; CAS registers the free peptide - per COA | 14 |
Physicochemical Solubility & Storage Parameters
| Product Code | Appearance | Long-term Storage | Short-term Storage | Solution Stability | Solid Powder Stability |
| PEP-PEP78-01 | White to off-white powder | Store at -20°C or below (recommended -20°C±5°C), dry, sealed, light-protected (contains 1 Met - prevent oxidation); aliquot to avoid repeated freeze-thaw | 2–8°C, sealed, dry and light-protected, for days to weeks (short-term transport/storage) | Contains 1 Met - avoid oxidation on reconstitution: use deoxygenated solvents, avoid oxidants and light. TargetMol recommends pre-dissolving in DMSO then diluting with ddH2O/PEG300/SBE-β-CD etc. Moderate aqueous solubility (polar residues). Prepare fresh; aliquot at -20°C; avoid repeated freeze-thaw | powder stable for 1-2 years when dry, light-protected and sealed; protect from moisture and oxidation; aliquot promptly after opening |
Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Pathways |
| PEP-PEP78-01 | CAS 132116-62-2 is the 14-mer TMRKPRSGNPDVAN; vendors market it as 'Peptide 78/ENA-78(CXCL5)' but it is not the full-length 78-aa chemokine. | Marketed by vendors as an ENA-78/CXCL5-like CXC chemokine that signals via CXCR2 to chemoattract and activate neutrophils (e.g. in rheumatoid arthritis synovial fluid). Caveat: the CAS-registered structure (CAS 132116-62-2) is the 14-mer TMRKPRSGNPDVAN (MW ~1542.7), not the full-length 78-aa CXCL5 (~8.3 kDa); the chemotactic/activation description is vendor boilerplate from full-length ENA-78 literature and must be applied cautiously to this 14-mer. | Inflammation/neutrophil biology,Chemokine research (molecule caveat),Peptide tool compound | Vendors cite CXCR2 (independent validation of this 14-mer's CXCR2 activity is lacking) |
