Handling & Stability
Storage. Store dry lyophilized powder desiccated at -20°C to -80°C, protected from moisture and ambient light exposure.
Solubility. Freely soluble in sterile deionized water (≥ 25 mg/mL) and sterile Phosphate-Buffered Saline (PBS, pH 7.4, ≥ 15 mg/mL) for in vitro laboratory assay delivery.
- Handling & Degradation Parameters: Exhibits high structural stability in neutral aqueous solutions; avoid excessive aeration or high-shear vortexing to prevent mechanical denaturation, and aliquot into single-use fractions to eliminate freeze-thaw degradation cycles.
Mechanism & Literature
Structural Origin: Synthetic 15-amino acid peptide derived from a partial sequence isolated from endogenous human gastric juice protein. Engineered as a linear pentadecapeptide with a prominent tri-proline repeating segment (Pro3-Pro4-Pro5) conferring relative resistance to enzymatic hydrolysis in biochemical assay environments.
Cellular Pathways Investigated: Extensively profiled in in vitro cellular models (including human umbilical vein endothelial cells [HUVECs] and tendon-derived fibroblasts) to analyze modulation of the focal adhesion kinase (FAK)-paxillin phosphorylation axis, activation of Early Growth Response-1 (Egr-1), and downstream regulation of vascular endothelial growth factor receptor 2 (VEGFR2) transcription and collagen type I/III synthesis.

Technical Laboratory FAQs
What is the sequence origin and primary structure of BPC-157?
BPC-157 is a 15-amino acid synthetic peptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, corresponding to a stable fragment derived from gastric juice protein.
Why does BPC-157 exhibit stability in diverse in vitro pH environments?
The peptide's conformation is stabilized by its contiguous tri-proline motif (Pro3-Pro4-Pro5), which creates a rigid polyproline II secondary structure that limits accessibility to non-specific laboratory endopeptidases.
What solvent conditions are standard for preparing in vitro BPC-157 stock assays?
Sterile deionized water or sterile PBS (pH 7.4) provides immediate dissolution at concentrations exceeding 15 mg/mL, providing a neutral carrier solution for cell culture and biochemical modeling.
