The Evolution of Endotoxin Detection

At the frontier of endotoxin testing with recombinant technology.

One of our main missions is to innovate in the field of endotoxin detection, with a strong focus on patient safety. Our ENDONEXT™ Endotoxin Detection Assays based on recombinant Horseshoe Crab Factor C (rFC) give you the performance needed for fast and efficient in-process control, product release and solutions for even the most challenging matrices throughout your manufacturing process. Using synthetic rFC instead of blood cells from Horseshoe crabs not only ensures ecological sustainability and security of supply, but also unprecedented accuracy, sensitivity and lot-to-lot consistency.


Main Benefits :

●    100% endotoxin specificity, no false positives from ß-Glucan or interference due to colored or turbid samples.
●    Approved for use and validated in the same way as LAL (limulus amebocyte lysate) , following pharmacopoeia BET (Bacterial Endotoxin Test) chapters.
●    Higher precision and rate of valid results combined with time-saving sensitivity and lot-to-lot consistency.

100% endotoxin specificity, no false positives from ß-Glucan or interference due to colored or turbid samples. 


Higher precision and rate of valid results combined with time-saving, state-of-art sensitivity and lot-to-lot consistency.

ICO user -friendly

Easy automation with commercially available robotic liquid-handling systems.


Ecological sustainability & security of supply with rFC instead of using an animal source.


Cost efficiency with short Return of Investment (ROI) and reduced waste fulfilling 3R principles.


Fluorescence end-point assays in 96-well microplate format with methodologies similar to kinetic chromogenic LAL.


Approved for use and validated in the same way as LAL, following pharmacopoeia BET chapters.

Product tests

We’re making endotoxin testing faster, easier and more ecologically friendly by mimicking nature, not exploiting it. Our assays enable confident in-process control and product release decisions of pharmaceutical products and medical devices.
