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.

## What is the Chromogenic Endotoxin Quant Kit?

The Chromogenic Endotoxin Quant Kit is a highly sensitive and specific assay designed for the quantitative measurement of bacterial endotoxins. This kit utilizes a chromogenic substrate that produces a yellow color when cleaved by the endotoxin-activated enzyme cascade, allowing for precise spectrophotometric measurement.

### Key Features of the Kit

– High sensitivity with detection limits as low as 0.005 EU/mL
– Wide linear range for accurate quantification
– Rapid results within 60-90 minutes
– Compatibility with various sample types
– Excellent reproducibility and precision

## How the Chromogenic Assay Works

The assay is based on the Limulus Amebocyte Lysate (LAL) principle, which mimics the clotting mechanism of horseshoe crab blood. When endotoxins are present, they activate a series of enzymatic reactions that ultimately cleave the chromogenic substrate, producing a measurable color change.

### Step-by-Step Procedure

1. Sample preparation and dilution
2. Reaction with LAL reagent
3. Incubation with chromogenic substrate
4. Stop reaction and measure absorbance
5. Calculate endotoxin concentration using standard curve
