Cys-PKKKRKV

Cys-PKKKRKV is a 7-residue synthetic peptide with the sequence Pro-Lys-Lys-Lys-Arg-Lys-Val. The sequence contains 4 Lys and 1 Arg residues, contributing cationic character. 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.
