Manufacturing & Quality Control
Production Process
BNP brain natriuretic peptide is manufactured using solid-phase peptide synthesis (SPPS) on automated synthesizers. The process begins with Fmoc chemistry on a Rink amide resin, followed by sequential amino acid coupling, deprotection, and cleavage. Crude peptide is then precipitated and lyophilized before purification.
Purification & Third-Party Testing
Reversed-phase high-performance liquid chromatography (RP-HPLC) is employed to achieve target purity levels. Each batch undergoes mass spectrometry (MS) for molecular weight confirmation and amino acid analysis for sequence fidelity. Third-party laboratories verify endotoxin levels below 0.5 EU/mg and bioburden counts under 100 CFU/g.
- ISO 9001:2015 certified manufacturing facility
- GMP-compliant cleanroom environment (Class 100,000)
- Certificate of Analysis (CoA) provided per lot
- MSDS available for safe handling documentation
- Stability studies conducted under ICH guidelines
