# Chromogenic Endotoxin Quantification Kit

## Introduction to Endotoxin Detection

Endotoxins are lipopolysaccharides (LPS) found in the outer membrane of Gram-negative bacteria. These molecules can trigger strong immune responses in humans and animals, making their detection crucial in pharmaceutical production, medical device manufacturing, and research laboratories.

## What is the Chromogenic Endotoxin Quant Kit?

The Chromogenic Endotoxin Quant Kit is a highly sensitive and specific tool designed for the quantitative measurement of endotoxin levels in various samples. This kit utilizes a chromogenic substrate that produces a color change proportional to the endotoxin concentration present in the sample.

### Key Features of the Kit

– High sensitivity with detection limits as low as 0.005 EU/mL
– Wide linear range for accurate quantification
– Compatibility with various sample types
– Rapid results compared to traditional methods
– Standardized protocol for consistent performance

## How the Kit Works

The Chromogenic Endotoxin Quant Kit operates through a series of enzymatic reactions:

– Endotoxin activates a pro-clotting enzyme in the presence of specific factors
– The activated enzyme cleaves a chromogenic substrate
– The resulting color change is measured spectrophotometrically
– The absorbance correlates with endotoxin concentration

## Applications in Various Industries

This quantification kit finds applications across multiple sectors:

### Pharmaceutical Industry

Ensuring the safety of injectable drugs and medical devices by detecting endotoxin contamination.
