Endotoxin Testing Services
In conditions where the body is exposed to lipopolysaccharides (LPS) excessively or systemically, a systemic inflammatory reaction may occur, leading to multiple pathophysiological effects. Therefore, it is important to detect and remove endotoxin from multiple products such as injectables, drugs, and other biological and pharmaceutical products. With extensive research on endotoxin and the art technology in this field, Creative Biolabs provides endotoxin testing to ensure reliable, efficient, and sustainable testing of bacterial endotoxin.
Introduction of Endotoxins
Endotoxins, also known as LPS, are derived from the cell membranes of Gram-negative bacteria and are responsible for their organization and stability. Endotoxins are continuously released into the environment, which happens with cell death, growth, and division. Endotoxins do not act directly against cells or organs but through activation of the immune system, especially through the monocytes and macrophages, with the release of a range of pro-inflammatory mediators, such as tumor necrosis factor (TNF), interleukin (IL)-6, and IL-1. Therefore, endotoxins are found almost everywhere and elicit a wide variety of pathophysiological effects.

Publication
Endotoxins consist of a hydrophilic polysaccharide moiety, which is covalently linked to a hydrophobic lipid moiety (lipid A). Endotoxins from most species are composed of three distinct regions: the O-antigen region, a core oligosaccharide, and lipid A. The lipid A is responsible for most of the biological activities of endotoxin, which means toxicity.

FAQs
Which assay—LAL or rFC—is more suitable for my novel therapeutic protein?
Both LAL and rFC are highly sensitive and validated. The optimal choice depends entirely on your product's specific matrix, regulatory market, and long-term sustainability goals.
How do you handle product-related interference that often yields false results?
Creative Biolabs rigorously performs inhibition/enhancement testing (IET) to determine the maximum valid dilution (MVD). By testing at or above the MVD, we neutralize interfering factors, ensuring the final endotoxin result is accurate, reliable, and compliant.
Beyond testing, can you help us with depyrogenation validation?
We provide comprehensive depyrogenation validation (e.g., dry heat, chemical) to confirm an effective at least a 3-log reduction of endotoxins, ensuring compliance and process control for reusable components.
