Peptide, C-Terminal Fragment

Peptide, C-Terminal Fragment is a 4-residue synthetic peptide with the sequence Pro-Gln-Arg-Phe. C-terminal amidation removes the terminal carboxylate charge. 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.
