Kinetic Chromogenic Assay Reagents

Endochrome-K™, our 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 kinetic chromogenic assay reagent provides heightened sensitivity for more accurate results, graterlinearity for endtoxin analyses, and superior interference resistance. Our LAL kinetic chromogenic reagent is desinged 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.
