WRNWDVYKVIYYKDGEALKYW-Ahx-Cys

WRNWDVYKVIYYKDGEALKYW-Ahx-Cys is a 21-residue synthetic peptide with the sequence Trp-Arg-Asn-Trp-Asp-Val-Tyr-Lys-Val-Ile-Tyr-Tyr-Lys-Asp-Gly-Glu-Ala-Leu-Lys-Tyr-Trp. An Ahx spacer separates the peptide from an attached label or handle. The sequence contains 3 Lys and 1 Arg residues, contributing cationic character; contains 7 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.
