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 inflammatory responses when introduced into the bloodstream, 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 measurement of endotoxin levels in various samples. This kit utilizes a chromogenic method that provides accurate and reproducible results, making it an essential tool for quality control in manufacturing processes.

### Key Features of the Kit

– High sensitivity with detection limits as low as 0.005 EU/mL
– Wide dynamic range for various sample types
– Excellent correlation with the Limulus Amebocyte Lysate (LAL) test
– Simple and rapid procedure with colorimetric readout
– Suitable for both research and industrial applications

## How the Chromogenic Endotoxin Quant Kit Works

The kit operates on the principle of endotoxin-activated coagulation enzymes cleaving a specific chromogenic substrate. This reaction produces a yellow-colored product that can be measured spectrophotometrically at 405 nm. The intensity of the color is directly proportional to the endotoxin concentration in the sample.

### Step-by-Step Procedure

1. Sample preparation and dilution
2. Incubation with the reagent mixture
3. Addition of chromogenic substrate
4. Measurement of absorbance at 405 nm
5. Calculation of endotoxin concentration using the standard curve
