Endosafe® Endotoxin Testing

The bacterial endotoxin test has evolved into a highly sensitive and exquisitely specific in vitro assay that is used to protect humans from contaminated medical devices, cellular therapies and parenteral products. As the most sensitive and robust assay available, limulus amebocyte lysate (LAL) has transformed from a qualitative gel-clot assay to a 15-minute quantitative assay available right on the production floor. Charles River has been at the forefront in the evolution of endotoxin testing, investing in the development of new technologies and innovative products to improve the quality of testing and accelerate the development process. We’ve purposely built our portfolio of FDA-licensed products for rapid and traditional bacterial endotoxin testing to reduce retest rates and improve turnaround times so you can make prompt, confident decisions about the safety of your products.
