YLKIWQKIIGWNL-NH2

YLKIWQKIIGWNL-NH2 is a 13-residue synthetic peptide with the sequence Tyr-Leu-Lys-Ile-Trp-Gln-Lys-Ile-Ile-Gly-Trp-Asn-Leu. C-terminal amidation removes the terminal carboxylate charge. The sequence 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.

• 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.
