KKDAGLYFFRLERGKTKYNYMWDKMTLVVT

KKDAGLYFFRLERGKTKYNYMWDKMTLVVT is a 30-residue synthetic peptide with the sequence Lys-Lys-Asp-Ala-Gly-Leu-Tyr-Phe-Phe-Arg-Leu-Glu-Arg-Gly-Lys-Thr-Lys-Tyr-Asn-Tyr-Met-Trp-Asp-Lys-Met-Thr-Leu-Val-Val-Thr. The sequence contains 5 Lys and 2 Arg residues, contributing cationic character; contains 6 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.
