Kinetic Turbidimetric Reagents
Our two kinetic turbidimetric LAL endotoxin test reagents, KTA and KTA2, yield quantitative endotoxin values when used with a microplate reader equipped with endotoxin-measuring software. Both reagents are buffered to provide significant interference-resistance properties and are FDA-licensed for use in product release testing. Our kinetic turbidimetric endotoxin test reagents are buffered to give the best interference-resistance properties.
With KTA and KTA2, you will receive accurate endotoxin results on even your most difficult products in the same amount of time it takes to run a gel-clot LAL test. Our exceptional kinetic turbidimetric endotoxin test formulations are licensed for kinetic and gel-clot analyses and allow for a direct correlation between the methods.
Cartridge, Kinetic, or Gel-Clot?
Whatever you're testing, whichever testing method you choose, Charles River's Endosafe® reagents have you covered. See which one is best for your organization.
KTA
Our traditional kinetic turbidimetric assay reagent (KTA) is suitable for both kinetic and gel-clot analyses and permits a direct correlation between LAL methods.
