Molecular Characteristics

Complete Specifications:

  • CAS Registry Number: 137525-51-0
  • Molecular Weight: 1,419.55 Da
  • Molecular Formula: C₆₂H₉₈N₁₆O₂₂
  • Amino Acid Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
  • PubChem CID: 9941957
  • Peptide Classification: Synthetic pentadecapeptide
  • Appearance: White to off-white lyophilized powder
  • Solubility: Water, bacteriostatic water, phosphate buffered saline

The peptide’s 15-amino acid structure contributes to its unique stability profile. Three proline residues within the sequence (positions 3, 4, 5, and 8) introduce conformational constraints that may contribute to enzymatic resistance. The sequence includes both acidic residues (glutamic acid, aspartic acid) and basic residues (lysine), creating an overall charge distribution that influences solubility and potential receptor interactions.

Laboratory Handling and Storage Protocols

Lyophilized Powder Storage:

  • Store at -20°C to -80°C in original sealed vial
  • Protect from light exposure and moisture
  • Desiccated storage environment recommended
  • Stability data available for 12+ months at -20°C

Reconstitution Guidelines:

  • Reconstitute with sterile water, bacteriostatic water (0.9% benzyl alcohol), or appropriate buffer
  • Add solvent slowly down vial side to minimize foaming
  • Gentle swirling motion recommended (avoid vigorous shaking)
  • Allow complete dissolution before use (typically 1-2 minutes)
  • Final pH should be 7.0-8.0 for optimal stability

Reconstituted Solution Storage:

  • Short-term storage: 4°C for up to 7 days
  • Long-term storage: -20°C in aliquots to avoid freeze-thaw cycles
  • Single-use aliquots recommended to maintain peptide integrity
  • Avoid repeated freeze-thaw cycles (maximum 2-3 cycles)

Enhanced Stability Profile:
BPC-157 demonstrates superior stability compared to many research peptides. Studies document stability at room temperature for extended periods, resistance to gastric acid degradation (pH 1.5), and maintained biological activity across diverse pH ranges. This unusual stability profile allows for more flexible experimental protocols.

Quality Assurance and Analytical Testing

Each BPC-157 batch undergoes comprehensive analytical characterization:

Purity Analysis:

  • High-Performance Liquid Chromatography (HPLC): ≥98% purity
  • Analytical method: Reversed-phase HPLC with UV detection at 220nm
  • Multiple peak integration to ensure accurate purity determination

Structural Verification:

  • Electrospray Ionization Mass Spectrometry (ESI-MS): Confirms molecular weight 1,419.55 Da
  • Amino acid analysis: Verifies sequence composition
  • Peptide content determination: Quantifies actual peptide content by weight

Contaminant Testing:

  • Bacterial endotoxin: <5 EU/mg (LAL method)
  • Heavy metals: Below detection limits per USP standards
  • Residual solvents: TFA and acetonitrile within acceptable limits
  • Water content: Karl Fischer titration (<8%)

Documentation:

  • Certificate of Analysis (COA) provided with each batch
  • Third-party analytical verification available upon request
  • Stability data documented for recommended storage conditions
  • Batch-specific QC results traceable by lot number
