Chromogenic Endotoxin Quantification Kit: A Reliable Tool for Endotoxin Detection

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

## Introduction to Endotoxins and Their Detection

Endotoxins, also known as lipopolysaccharides (LPS), are toxic components 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, medical device, and biotechnology industries.

## What is the Chromogenic Endotoxin Quant Kit?

The Chromogenic Endotoxin Quant Kit is a highly sensitive and specific tool designed for the quantitative detection of endotoxins. This kit utilizes a chromogenic substrate that produces a color change in the presence of endotoxins, allowing for precise measurement through spectrophotometric analysis.

### Key Features of the Kit

– High sensitivity with detection limits as low as 0.005 EU/mL
– Wide dynamic range for accurate quantification
– Compatibility with various sample types
– Simple and rapid procedure
– Excellent correlation with the Limulus Amebocyte Lysate (LAL) test

## How the Chromogenic Endotoxin Quant Kit Works

The assay is based on the principle of endotoxin-activated coagulation enzymes cleaving a specific chromogenic substrate. This reaction produces a yellow-colored product (p-nitroaniline) whose absorbance can be measured at 405 nm. The intensity of the color is directly proportional to the endotoxin concentration in the sample.

### Step-by-Step Procedure

– Prepare standard solutions and samples
– Mix with the provided reagents
– Incubate at 37°C for a specified time

– Stop the reaction with acetic acid
– Measure absorbance at 405 nm
– Calculate endotoxin concentration using the standard curve

## Applications of the Chromogenic Endotoxin Quant Kit

This versatile kit finds applications in various fields:

### Pharmaceutical Industry

– Quality control of parenteral drugs
– Testing of raw materials and excipients
