Ac-FAEKFKEAVKDYFAKFWD

Ac-FAEKFKEAVKDYFAKFWD is a 18-residue synthetic peptide with the sequence Phe-Ala-Glu-Lys-Phe-Lys-Glu-Ala-Val-Lys-Asp-Tyr-Phe-Ala-Lys-Phe-Trp-Asp. The sequence contains 4 Lys and 0 Arg residues, contributing cationic character; contains 6 aromatic residues; has a relatively high hydrophobic-residue fraction that can influence aqueous solubility and surface adsorption. These sequence-derived properties describe the reagent chemically; no specific biological activity is assigned without product-specific experimental evidence.

• LC-MS/HPLC analytical method development
• sequence-specific assay controls

Sequence-derived chemical properties support reagent selection and experimental planning but do not establish biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended conditions.
