alpha-Substance IB

alpha-Substance IB is a 6-residue synthetic peptide with the sequence Arg-Gly-Pro-Phe-Pro-Ile. The sequence is Gly/Pro-rich, a composition that can influence local backbone flexibility. 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.
