Introduction of Endotoxin Detection Services
Endotoxin detection is mandated for all injectable products, focusing on lipopolysaccharide (LPS), a potent bacterial pyrogen that causes fever and septic shock, with detection methods targeting the lipid A moiety. Current research underscores that the non-specific binding of LPS to therapeutic proteins (masking) poses a significant challenge, frequently leading to false negative results. Accurate testing requires specialized sample preparation to break these molecular interactions. Understanding this masking phenomenon is critical for ensuring safety and achieving precise, regulatory-compliant LPS quantification.
Overview of Our Services
Creative Biolabs has been committed to the development of endotoxin testing for many years. We employ sensitive, accurate, and rapid methods for endotoxin detection. We customize the most suitable assay for each project and use an assay or a combination of several assays to meet your requirements.
LAL Assay
Biosensor Technique
The biosensor technique is a kind of modern endotoxin detection method which will eventually replace the gold standard of RPT and LAL tests.
Learn More →Recombinant Factor C Assay
The rFC assay, an endotoxin sensitive synthetic protein, is cloned from factor C DNA to use as an alternative in vitro LAL test.
Learn More →Monocyte Activation Test
The monocyte activation test allows the detection of the full range of pyrogens including endotoxins and non-endotoxin pyrogens to use as a human alternative in vitro RPT.

FAQs
My current LAL test occasionally shows high variability. How does the rFC assay improve this consistency?
The Rfc assay uses a synthetic, chemically-defined protein, ensuring unparalleled batch-to-batch consistency and high stability. This eliminates biological variability, providing cleaner and more reproducible quantitative data required for rigorous QC.
If my product is known to interfere with LAL (matrix effect), can you still test it?
Absolutely. We specialize in method suitability testing, which involves developing proprietary buffer systems and dilution protocols to neutralize inhibitory or enhancing components in your matrix. Our goal is to ensure a validated method with a spike recovery of 50%–200%.
Is the MAT a suitable replacement for the rabbit pyrogen test (RPT)?
Yes, MAT is the globally accepted in vitro alternative to RPT and is scientifically superior. It detects the full spectrum of pyrogens by measuring human cytokine release, providing a result highly relevant to human physiology.
