- Cleavage and Deprotection: The peptide is cleaved from the resin using TFA-based cocktails, removing side-chain protecting groups.
- Purification: Preparative reverse-phase HPLC (RP-HPLC) separates the target peptide from truncated sequences and impurities.
- Lyophilization: The purified peptide is freeze-dried to a stable powder under controlled vacuum conditions.
- Quality Control Testing: Each batch undergoes HPLC purity analysis, mass spectrometry (MS) for molecular weight confirmation, and amino acid analysis for sequence verification.
Third-Party Testing & Certification
- HPLC Purity Report: Certificate of analysis with ≥98% purity and impurity profile.
- Mass Spectrometry: ESI-MS or MALDI-TOF confirming molecular weight within ±0.5 Da.
- Endotoxin Testing: LAL assay ensuring levels below 1.0 EU/mg for research use.
- Heavy Metal Analysis: ICP-MS screening for lead, arsenic, cadmium, and mercury below ICH Q3D limits.
- Stability Studies: Accelerated and real-time stability data supporting shelf-life claims.
