Scientific Background | PRFFHYILFYRVR is a 13-residue synthetic peptide with the sequence Pro-Arg-Phe-Phe-His-Tyr-Ile-Leu-Phe-Tyr-Arg-Val-Arg. The sequence is enriched in basic residues (0 Lys and 3 Arg), giving the sequence a cationic character under many aqueous conditions; contains 5 aromatic residues (Phe/Trp/Tyr), which can contribute to hydrophobic or aromatic interactions; contains a relatively high fraction of hydrophobic residues, which can influence solubility and nonspecific adsorption. No specific receptor, enzyme, pathway, disease association, or biological activity is assigned to this peptide without product-specific experimental evidence. |
Experimental Notes | Sequence-derived chemical properties are provided to support reagent selection and experimental planning. They do not establish a biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended experimental conditions. |
