# Endotoxin Detection Using Gel-Clot Assay Reagents

## Introduction to Gel-Clot Endotoxin Reagents

The gel-clot assay is one of the most traditional and reliable methods for endotoxin detection. Gel-clot endotoxin reagents play a crucial role in this process, providing the necessary components to detect and quantify bacterial endotoxins in various samples.

## How Gel-Clot Endotoxin Reagents Work

Gel-clot reagents contain Limulus Amebocyte Lysate (LAL), which reacts specifically with bacterial endotoxins. When endotoxins are present in a sample, they activate the coagulation cascade in the LAL, resulting in the formation of a gel clot. This visible change indicates the presence of endotoxins.

### Key Components of Gel-Clot Reagents

– Limulus Amebocyte Lysate (LAL)
– Buffer solutions
– Control standard endotoxin (CSE)
– Reaction tubes
