Tissue-research peptidesBPC-157
Synthetic 15-amino-acid peptide (GEPPPGKPADDAGLV) supplied as a lyophilized powder for in-vitro laboratory characterization.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide with the amino-acid sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is described in the literature as a fragment of a protein first characterized from human gastric juice, and it is chemically unusual among small peptides for its reported stability under acidic conditions in physicochemical studies. Ascend Labs supplies it as a lyophilized research material for cell-culture and cell-free assay work.
Structure and class
No single high-affinity receptor has been assigned to BPC-157; published in-vitro work treats it as a broadly interacting peptide whose behavior depends strongly on assay system, concentration and exposure time. For laboratory planning this means results should be interpreted against matched vehicle controls and verified reagent identity rather than assumed to transfer between experimental systems.
Chemistry and analytical notes
Notes cover structural and analytical chemistry; each link runs a live PubMed search for the topic.
Analytical identity
Identity and purity are established by reversed-phase HPLC and MS; the batch certificate of analysis reports both, so the material used in an experiment can be traced to its analytical record.
Search PubMedPhysicochemical stability
Solution stability of BPC-157 has been examined in analytical studies, which inform the storage and freeze–thaw guidance used in laboratory protocols.
Search PubMedIn-vitro assay contexts
Published in-vitro studies use BPC-157 in cell-culture and cell-free systems; experimental-design notes emphasize controls and documentation of passage, medium and exposure time.
Search PubMedHandling & storage
Store lyophilized at −20°C, protected from light and moisture. Reconstitute with reconstitution-grade sterile water under aseptic technique; keep the solution at 2–8°C, avoid repeated freeze–thaw cycles and use within your protocol's stability window. For laboratory research use only — not for human or veterinary use.
