# Gel Clot Endotoxin Test Kit: Reliable Detection for Bacterial Endotoxins
## Introduction to Bacterial Endotoxins
Bacterial endotoxins, also known as lipopolysaccharides (LPS), are toxic components found in the outer membrane of Gram-negative bacteria. These substances 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 widely used method for detecting and quantifying bacterial endotoxins. This test is based on the principle of coagulation reaction between endotoxins and Limulus Amebocyte Lysate (LAL), a substance derived from horseshoe crab blood.
### How the Test Works
When endotoxins are present in a sample, they react with the LAL reagent to form a gel clot. The formation of this clot indicates the presence of endotoxins above a certain threshold. The test can be performed as:
