Recombinant Collagen Endotoxins Analysis Service
Endotoxins, primarily lipopolysaccharides (LPS) originating from bacterial outer membranes, pose significant safety risks in recombinant collagen-based products. Contamination may occur during expression, purification, or packaging, and even trace levels of endotoxins can elicit strong immune responses, jeopardizing the clinical utility of biomedical products.
MtoZ Biolabs offers a dedicated Recombinant Collagen Endotoxins Analysis Service that employs the Limulus Amebocyte Lysate (LAL) assay to deliver high-sensitivity, quantitative detection across all production stages—from upstream intermediates to final drug substances. Our service ensures your recombinant collagen meets stringent biosafety standards for therapeutic, cosmetic, and tissue engineering applications.

FAQ
Q1: How long does the endotoxin testing process take?
Testing typically requires 2–3 weeks, covering sample handling, preparation, assay execution, and data reporting. We aim to deliver timely, accurate results aligned with your production or regulatory timeline.
Q2: What is the principle of the LAL assay in endotoxin detection?
The LAL assay utilizes an enzyme cascade derived from horseshoe crab amebocytes. When exposed to endotoxins (LPS), this system triggers coagulation reactions measurable by gel clot formation, turbidity change, or chromogenic signal, providing a sensitive and specific detection method.
