Endotoxin and Pyrogen Test Kits and Software - a rapidmicrobiology Special Focus


Endotoxin testing is an important process in various industries, including pharmaceuticals, medical devices, and biotechnology to ensure the safety and quality of products, as endotoxins can cause severe adverse reactions in humans. The Limulus Amebocyte Lysate (LAL) assay, is widely used for endotoxin detection. LAL is a mixture of proteins obtained from the amebocytes or cells of the horseshoe crab and causes a clotting reaction in the presence of endotoxins.

In this rapidmicrobiology special focus, we showcase the latest commercially available reagents, kits and instrumentation available for endotoxin testing.

When it comes to endotoxin testing, by whatever method, it is essential to have all labware, reagents, and laboratory water known to be free of endotoxin contamination. Endotoxin contamination in lab equipment and water supply can lead to false positives requiring the assay to be repeated, which is poor practice and not cost-effective, especially when dealing with expensive, short-life products such as cell and gene therapies. Dr. Kunal Kureja, Application Scientist for Lab Water at Sartorius AG, discusses what type of ultrapure water is suitable for use in endotoxin analysis and how to validate and verify it is endotoxin-free.

Various forces including corporate sustainability commitments, a need to improve lot-to-lot reagent standardisation and difficult matrices are among the issues bringing about market demand for a replacement of horseshoe crab-sourced LAL. Sustainability can be improved by using reduced quantities of animal derived LAL - the CMD αBET™ system is a fully integrated endotoxin testing solution that uses just a few microlitres of reagent to deliver results in under half the time of traditional tests without compromising on sensitivity or performance.

Another solution is Recombinant Factor C (rFC) which has been available for a number of years, Factor C is one of the enzymes responsible for activating the LAL cascade in the presence of endotoxins. In traditional LAL assays, Factor C is extracted from horseshoe crab blood but rFC is a genetically engineered version of Factor C produced using recombinant DNA technology without the need to harvest from horseshoe crabs.

Recently introduced is recombinant LAL (rLAL) which again is a synthetic version of the LAL enzyme produced using recombinant DNA technology. Discover from endotoxin experts Timothy Francis and Hesham Rashed at FUJIFILM Wako Chemicals U.S.A more about the new PYROSTAR™ Neo rLAL and why laboratories should be considering changing from LAL to rLAL reagents for some or all of their endotoxin testing.

Reduce variability and rate of invalid results with high throughput automated and semi-automated systems such as the Endosafe® Nexus 200 and the ENDONEXT™ Endotoxin Detection Assay.

It's worth noting that specific brands and manufacturers may offer different software and kits, each with their unique features and capabilities. Therefore, it is advisable to consult the product documentation or contact the manufacturers for detailed information on their specific offerings.
