Neuropeptide K, porcine

Neuropeptide K is a 36 amino acid peptide that contains the Substance K sequence at its C-terminus. Neuropeptide K belongs to the tachykinin family. These active peptides excite neurons, provoke behaviorial responses, and are potent vasodilators and secretagogues.

Neuropeptide K, porcine is a 36-residue synthetic peptide with the sequence Asp-Ala-Asp-Ser-Ser-Ile-Glu-Lys-Gln-Val-Ala-Leu-Leu-Lys-Ala-Leu-Tyr-Gly-His-Gly-Gln-Ile-Ser-His-Lys-Arg-His-Lys-Thr-Asp-Ser-Phe-Val-Gly-Leu-Met. C-terminal amidation removes the terminal carboxylate charge. The sequence contains 4 Lys and 1 Arg residues, contributing cationic character. These sequence-derived properties describe the reagent chemically; no specific receptor, enzyme, pathway, disease association, or 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 experimental conditions.
