Quality control (QC) is a critical component of peptide manufacturing. This article introduces the key analytical methods and quality parameters used to assess peptide products.
The primary method for assessing peptide purity. Separates a sample into components and quantifies the relative abundance of the target peptide versus impurities. Purity is typically expressed as a percentage of the total peak area.
Combines HPLC separation with mass spectrometric detection to confirm peptide identity based on molecular weight. Essential for verifying that the correct peptide was synthesized.
Quantifies the amino acid composition of a peptide to confirm its identity and determine net peptide content.
The Limulus Amebocyte Lysate test detects bacterial endotoxins. Critical for injectable products, as endotoxins can cause fever, shock, and organ damage.
Confirms the absence of viable microorganisms. Required for all injectable pharmaceutical products.
Pharmaceutical peptide manufacturing requires documented quality systems including batch records, deviation management, change control, CAPA (Corrective and Preventive Action), and stability programs.
