KGPSQPTYPGDDAPVRDLIRFYRDLRRYLNVVTRHRY

KGPSQPTYPGDDAPVRDLIRFYRDLRRYLNVVTRHRY is a 37-residue synthetic peptide with the sequence Lys-Gly-Pro-Ser-Gln-Pro-Thr-Tyr-Pro-Gly-Asp-Asp-Ala-Pro-Val-Arg-Asp-Leu-Ile-Arg-Phe-Tyr-Arg-Asp-Leu-Arg-Arg-Tyr-Leu-Asn-Val-Val-Thr-Arg-His-Arg-Tyr. N-terminal acetylation neutralizes the terminal alpha-amino group. The sequence contains 1 Lys and 7 Arg residues, contributing cationic character; contains 5 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.
