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 of 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 production, medical device manufacturing, and research applications.

## What is the Chromogenic Endotoxin Quant Kit?

The Chromogenic Endotoxin Quant Kit is a highly sensitive and specific assay designed to measure endotoxin levels in various samples. This kit utilizes a chromogenic substrate that produces a color change in proportion 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 dynamic range for accurate quantification
– Compatibility with various sample types

– Rapid results compared to traditional methods
– Excellent reproducibility and reliability

## How the Chromogenic Assay Works

The chromogenic method is based on the activation of a proenzyme by endotoxin, which subsequently cleaves a synthetic chromogenic substrate. This reaction produces a yellow-colored compound that can be measured spectrophotometrically at 405 nm.

### Step-by-Step Process:

1. Sample preparation and dilution
2. Reaction with Limulus Amebocyte Lysate (LAL)
3. Addition of chromogenic substrate
4. Incubation period
5. Measurement of absorbance
6. Calculation of endotoxin concentration

## Applications of the Chromogenic Endotoxin Quant Kit

This versatile kit finds applications in multiple fields:

### Pharmaceutical Industry

– Quality control of parenteral drugs
– Testing of raw materials
– Monitoring of production equipment

### Medical Device Manufacturing

– Evaluation of implantable devices
– Testing of dialysis equipment
– Quality assurance of surgical instruments

### Research Laboratories
