Quantifying Endotoxins Via Absorbance Or Fluorescence In A Multimode Plate Reader

Endotoxin detection plays a central role in confirming the safety of pharmaceutical products, and modern approaches now offer more consistent, animal‑free alternatives to traditional LAL assays. At the core of today’s colorimetric and fluorescence‑based methods is recombinant Factor C, which activates in the presence of lipopolysaccharides (LPS) to generate a measurable signal tied directly to endotoxin concentration. Multimode plate readers enable rapid quantification by capturing absorbance or fluorescence outputs, supporting large sample sets with strong reproducibility. As organizations transition from LAL to recombinant methods, flexible platforms and software tools help streamline workflows, accommodate multiple kit formats, and support high‑throughput automation.
