ENDONEXT™ Endotoxin Detection Assays

Based on Recombinant Horseshoe Crab Factor C (rFC), the ENDONEXT range of assays by bioMérieux is the future of endotoxin testing systems. With improved specificity, better consistency, and a more efficient workflow, ENDONEXT technology also completely eliminates the need to harvest horseshoe crabs for their blood—ushering in a new era of smarter, more sustainable pharmaceutical quality control.

All ENDONEXT assays follow BET methodology and are validated according to standard pharmacopoeia criteria. rFC is included both in the European Pharmacopoeia chapter Ph. Eur. 5.1.10 as well as in the U.S. FDA Guidance for Industry: Pyrogen and Endotoxins Testing. The U.S. FDA recently also approved rFC for product release testing of Galcanezumab (Eli Lilly).

The ENDONEXT assay range:


NEW 2018: The rapid GO version of ENDOZYME II featuring GOPLATE™—a microplate pre-filled with required standard curve and positive product control concentrations (PPC).
