Kinetic Chromogenic LAL Test Reagents

Endochrome-K™, our kinetic chromogenic assay (KCA) facilitates your endotoxin screening with its ease of use and unique reagent stability. Featuring an optimized 0.001 EU/mL limit of detection formulation, our KCA provides increased sensitivity, greater linearity and superior interference resistance. Endochrome-K™ delivers quantitative endotoxin values in roughly an hour, and its use of reconstituted LAL allows for extended bench time and reuse, making it a highly cost-effective solution.
