Traditional Kinetic Chromogenic Assay Reagents

Endochrome-K™, our traditional LAL kinetic chromogenic assay (KCA) facilitates your endotoxin screening with its ease of use and unique reagent stability. Featuring an optimized 0.005 EU/mL sensitivity*, our traditional kinetic chromogenic assay reagent provides heightened sensitivity for more accurate results, greater linearity for endotoxin analyses, and superior interference resistance. Our traditional LAL kinetic chromogenic reagent is designed to enhance your kinetic chromogenic assay and rapidly deliver accurate results.

*Lower sensitivity lots available on request, reach out to your local representative if you require a more sensitive lysate.
