Structural Context
BPC-157 is a 15-residue polypeptide characterized by an exceptionally high proline content, with five proline residues distributed throughout the sequence. The presence of proline at positions 3, 4, 5, 8, and 12 introduces significant conformational constraint and distinct secondary structural tendencies. The combination of charged residues (Glutamic Acid, Lysine, and two Aspartic Acid residues) with hydrophobic residues (Proline, Alanine, Leucine, and Valine) creates a defined polarity profile suitable for analytical method development, chromatographic reference studies, and peptide solubility assessments in controlled laboratory environments.
Handling and Storage
The peptide is supplied in lyophilized (freeze-dried) powder form in a 10 mg vial. For optimal stability, store lyophilized material at or below -20°C. Protect from repeated freeze-thaw cycles, moisture, and prolonged exposure to light, heat, and humidity.
Research Applications
This product is manufactured and supplied as a chemical reference standard for in-vitro laboratory research applications including analytical method development, chromatographic reference studies, stability assessments, and peptide solubility testing in controlled laboratory environments.
