- Peptide Purity
- HPLC with UV detection at 214 nm
- ≥97% purity
- T0, T-mid, T-final
- Absence of degradation products and synthesis impurities
- Foundational for reproducibility. Purity below 95% invalidates dose calculations
- Molecular Weight
- MALDI-TOF mass spectrometry
- 1419.55 Da ±0.5 Da
- Post-reconstitution and study end
- Peptide structure remains intact without oxidation or hydrolysis
- Direct confirmation that administered compound was BPC-157, not a degraded analog
- Endotoxin Level
- LAL chromogenic assay
- ≤1.0 EU/mg
- Each batch before first use
- No gram-negative bacterial contamination
- Critical for inflammation or immune studies. Endotoxin is an uncontrolled confounder
- Sterility
- 14-day culture in dual media
- No microbial growth
- Pre-study and if contamination suspected
- Absence of viable bacteria or fungi in solution
- Prevents confounding from infection-driven immune responses in animal models
- Dosing Accuracy
- UV-Vis at 280 nm + gravimetric
- ±5% of target concentration
- Weekly for multi-dose vials
- Actual concentration matches calculated dose
- Small errors compound across protocols. 10% under-dosing means statistically underpowered results
- pH Stability
- Calibrated pH meter
- 5.0–6.5 range
- Post-reconstitution
- Solution pH supports peptide stability without accelerated degradation
- pH outside this range accelerates methionine oxidation and renders vials unstable within days
