Manufacturing & Quality Control
The production of peptides injections involves a multi-step process that demands rigorous quality assurance at every stage. Manufacturers employ solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by comprehensive purification and analytical testing.
Production Process
The synthesis begins with the sequential addition of protected amino acids to a solid resin support. Each coupling cycle includes deprotection, washing, and activation steps to ensure chain elongation efficiency. After complete assembly, the peptide is cleaved from the resin using trifluoroacetic acid (TFA) with appropriate scavengers to protect sensitive side chains.
Purification and Analysis
Crude peptides undergo preparative reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve target purity levels. The purified product is then lyophilized to remove solvents and water, resulting in a stable powder. Analytical methods include:
- Analytical HPLC for purity verification with UV detection at 214 nm and 280 nm
- Mass spectrometry (ESI-MS or MALDI-TOF) for molecular weight confirmation
- Amino acid analysis for composition verification
- Karl Fischer titration for residual moisture content (target <5%)
- Endotoxin testing using LAL assay for injectable-grade products
Certifications and Compliance
Reputable suppliers provide certificates of analysis (CoA) for each batch of peptides injections. Key certifications include:
- ISO 9001:2015 for quality management systems
