A quality control assay that detects bacterial lipopolysaccharide contamination in injectable peptide products to ensure safety.
Endotoxin testing is a critical quality control procedure that measures the level of bacterial endotoxins (lipopolysaccharides) in pharmaceutical and research products intended for injection. Endotoxins are components of Gram-negative bacterial cell walls that can trigger severe inflammatory responses even in nanogram quantities. The Limulus Amebocyte Lysate (LAL) test is the most widely used detection method, utilising a reagent derived from horseshoe crab blood that forms a clot in the presence of endotoxins. More recently, recombinant Factor C assays provide a synthetic alternative. ORYN subjects all peptide batches to endotoxin testing as part of its comprehensive quality control programme, with results documented on each Certificate of Analysis.
