Endotoxin Detection Kit for Gel Clot Method

The Gel Clot Endotoxin Test Kit is a reliable and widely used solution for detecting bacterial endotoxins in pharmaceutical products, medical devices, and other samples. This kit utilizes the gel clot method, a qualitative or semi-quantitative approach that is based on the clotting reaction of horseshoe crab (Limulus amebocyte lysate, LAL) in the presence of endotoxins.

Key Features of the Gel Clot Endotoxin Test Kit

This endotoxin detection kit offers several advantages:

  • High sensitivity to detect low levels of endotoxins

  • Simple and straightforward procedure

  • Cost-effective compared to other methods

  • No requirement for specialized equipment

  • Compliance with pharmacopeial standards (USP, EP, JP)

How the Gel Clot Method Works

The gel clot method involves mixing the sample with LAL reagent and incubating it at a controlled temperature (typically 37°C). If endotoxins are present, they activate the clotting enzyme cascade in the LAL, resulting in the formation of a gel clot. The presence or absence of this clot determines whether the sample passes or fails the endotoxin test.

Applications

The Gel Clot Endotoxin Test Kit is used in various industries:

  • Pharmaceutical manufacturing

  • Medical device production

  • Biotechnology research

  • Quality control laboratories

  • Hospital pharmacies

Advantages Over Other Methods

While there are other endotoxin detection methods available (such as chromogenic and turbidimetric), the gel clot method remains popular because:

  • It provides a clear visual endpoint

  • It’s less susceptible to interference from sample components

  • It requires minimal equipment

  • It’s suitable for field testing

Storage and Handling

Proper storage of the Gel Clot Endotoxin Test Kit is essential for maintaining its performance. The kit should be stored at -20°C or as recommended by the manufacturer. Once reconstituted, the LAL reagent should be used within the specified time frame to ensure accurate results.

For optimal performance, always follow the manufacturer’s instructions and include appropriate controls in each test run.
