KKDLVFNEYRMHKARMYSQ

KKDLVFNEYRMHKARMYSQ is a 19-residue synthetic peptide with the sequence Lys-Lys-Asp-Leu-Val-Phe-Asn-Glu-Tyr-Arg-Met-His-Lys-Ala-Arg-Met-Tyr-Ser-Gln. The sequence contains 3 Lys and 2 Arg residues, contributing cationic character; contains 3 aromatic residues. 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.
