RRWKIVVIRWRR

RRWKIVVIRWRR is a 12-residue synthetic peptide with the sequence Arg-Arg-Trp-Lys-Ile-Val-Val-Ile-Arg-Trp-Arg-Arg. The sequence contains 1 Lys and 5 Arg residues, contributing cationic character; 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.
