VPQKPKVSLNPPWNRIFKGENV-Ahx-Cys

VPQKPKVSLNPPWNRIFKGENV-Ahx-Cys is a 22-residue synthetic peptide with the sequence Val-Pro-Gln-Lys-Pro-Lys-Val-Ser-Leu-Asn-Pro-Pro-Trp-Asn-Arg-Ile-Phe-Lys-Gly-Glu-Asn-Val. An Ahx spacer separates the peptide from an attached label or handle. The sequence contains 3 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.
