Chromogenic Endotoxin Quantification Kit for Accurate Bacterial Toxin Measurement

# Chromogenic Endotoxin Quantification Kit for Accurate Bacterial Toxin Measurement

## 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 trigger severe immune responses in humans and animals, making their detection and quantification crucial in pharmaceutical, medical device, and biotechnology industries.

## The Importance of Accurate Endotoxin Measurement

Accurate endotoxin quantification is essential for:

• Ensuring product safety in pharmaceuticals and medical devices

• Maintaining compliance with regulatory standards (USP, EP, JP)

• Preventing pyrogenic reactions in patients

• Quality control in biopharmaceutical production

## Features of Chromogenic Endotoxin Quant Kit

Our Chromogenic Endotoxin Quant Kit offers several advantages over traditional methods:

### High Sensitivity
The kit provides detection limits as low as 0.005 EU/mL, making it suitable for even the most demanding applications.

### Colorimetric Detection
The chromogenic assay produces a yellow color that can be measured at 405-410 nm, offering excellent visual confirmation and spectrophotometric quantification.

### Simple Protocol
The straightforward procedure requires minimal training and can be completed in approximately 60 minutes.

## How the Chromogenic Assay Works

The assay is based on the activation of a pro-clotting enzyme by endotoxin, which then cleaves a chromogenic substrate to produce a yellow color. The intensity of this color is directly proportional to the endotoxin concentration in the sample.

## Applications Across Industries

This versatile kit finds applications in multiple fields:

• Pharmaceutical quality control

• Medical device testing

• Research laboratories

• Water quality monitoring

• Vaccine development

## Comparison with Other Methods

Unlike the traditional Limulus Amebocyte Lysate (LAL) gel-clot method, our chromogenic assay provides:

• Quantitative results rather than endpoint detection

• Higher sensitivity

• Better reproducibility

• Easier interpretation of results
