Chromogenic Endotoxin Quantification Kit

# Chromogenic Endotoxin Quantification Kit: A Reliable Solution for Endotoxin Detection

## Introduction to Endotoxin Detection

Endotoxins, also known as lipopolysaccharides (LPS), are toxic components found in the outer membrane of Gram-negative bacteria. These molecules can cause severe immune responses in humans and animals, making their detection crucial in pharmaceutical, medical device, and biotechnology industries. The Chromogenic Endotoxin Quantification Kit provides a sensitive and reliable method for measuring endotoxin levels in various samples.

## How the Chromogenic Endotoxin Quant Kit Works

The Chromogenic Endotoxin Quant Kit utilizes a chromogenic assay based on the Limulus Amebocyte Lysate (LAL) principle. This method offers several advantages:

– High sensitivity with detection limits as low as 0.005 EU/mL
– Quantitative results with excellent linearity
– Simple and rapid procedure compared to gel-clot methods
– Compatibility with various sample types

The assay works by activating the LAL enzyme cascade in the presence of endotoxin, ultimately leading to the cleavage of a chromogenic substrate that produces a yellow color. The intensity of this color, measured at 405-410 nm, is directly proportional to the endotoxin concentration in the sample.

## Key Features of the Kit

The Chromogenic Endotoxin Quant Kit includes all necessary components for accurate endotoxin measurement:

– LAL reagent optimized for chromogenic detection
– Chromogenic substrate specific for endotoxin detection
– Endotoxin standard for calibration
– Control standard endotoxin (CSE)
– Sample preparation reagents
– Detailed protocol and data analysis instructions

## Applications of the Chromogenic Assay
