E-Toxate reagent derived from Limulus polyphemus is widely used in the pharmaceutical and biotechnology industries for detecting bacterial endotoxins. It is a critical component of the Limulus Amebocyte Lysate (LAL) test, which ensures the safety of injectable drugs, medical devices, and other sterile products by identifying the presence of harmful endotoxins. This reagent is particularly valuable in quality control processes, as it provides highly sensitive and reliable results, helping to meet regulatory standards such as those set by the FDA and USP. Additionally, it is utilized in research laboratories to study endotoxin-related immune responses and to develop safer therapeutic products. Its application is essential in maintaining the sterility and safety of products used in healthcare.
