# Gel Clot Endotoxin Test Kit for Bacterial Endotoxin Detection
## Introduction to Bacterial Endotoxin Detection
Bacterial endotoxins are lipopolysaccharides (LPS) found in the outer membrane of Gram-negative bacteria. These toxins can cause severe reactions when introduced into the bloodstream, making their detection crucial in pharmaceutical and medical device manufacturing.
## What is a Gel Clot Endotoxin Test Kit?
The Gel Clot Endotoxin Test Kit is a reliable and widely used method for detecting bacterial endotoxins. This qualitative test is based on the principle of coagulation of horseshoe crab (Limulus amebocyte lysate or LAL) in the presence of endotoxins.
### How the Gel Clot Method Works
The test involves mixing the sample with LAL reagent and incubating it at 37°C for a specified time. If endotoxins are present, a gel clot forms, indicating a positive result. The sensitivity of the test is determined by the lowest concentration of endotoxin that causes gel formation.
