FKVATPYSLYVCPEGQNVTL

FKVATPYSLYVCPEGQNVTL is a 20-residue synthetic peptide with the sequence Phe-Lys-Val-Ala-Thr-Pro-Tyr-Ser-Leu-Tyr-Val-Cys-Pro-Glu-Gly-Gln-Asn-Val-Thr-Leu. The sequence contains 1 cysteine residue, allowing thiol/disulfide chemistry when available; contains 3 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.

• thiol-selective conjugation or immobilization studies
• 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.
