PE-22-28 was specifically designed for improved stability over spadin, with a duration of action of approximately 23 hours compared to spadin's 7 hours
PMC 11050313
Peptide Synthesis and Purification Solid-phase peptide synthesis method Synthesis process: The synthesis of BPC 157 usually adopts the solid-phase peptide synthesis method, and the polypeptide chain is constructed by gradually adding amino acid residues
