Chromogenic Endotoxin Quantification Kit for Accurate Bacterial Toxin Detection

# Chromogenic Endotoxin Quantification Kit for Accurate Bacterial Toxin Detection

## Introduction to Endotoxin Detection

Endotoxins, also known as lipopolysaccharides (LPS), are toxic components found in the outer membrane of Gram-negative bacteria. These bacterial toxins can cause severe inflammatory responses in humans and animals, making their detection crucial in pharmaceutical, medical device, and food safety applications.

## Understanding 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. This innovative kit utilizes a chromogenic substrate that reacts with endotoxin-activated enzymes, producing a color change proportional to the endotoxin concentration.

### Key Features of the Kit

– High sensitivity with detection limits as low as 0.005 EU/mL
– Wide dynamic range for accurate quantification
– Rapid results compared to traditional methods
– Excellent reproducibility and precision

– Compatibility with various sample matrices

## How the Chromogenic Assay Works

The assay is based on the activation of a pro-clotting enzyme by endotoxin through a series of enzymatic reactions. The activated enzyme then cleaves a specific chromogenic substrate, releasing p-nitroaniline (pNA) which produces a yellow color measurable at 405 nm.

### Step-by-Step Procedure

1. Sample preparation and dilution
2. Reaction with Limulus Amebocyte Lysate (LAL)
3. Addition of chromogenic substrate
4. Incubation at 37°C
5. Measurement of absorbance
6. Calculation of endotoxin concentration

## Applications in Various Industries
