Importance of Endotoxin Testing for Nucleic Acid Drugs

Bacterial endotoxins, found in Gram-negative bacteria cell walls, are released upon bacterial death or self-digestion. High bloodstream levels can cause serious reactions, like fever or septic shock. In nucleic acid drugs, endotoxins may stem from water, materials, or equipment used in production, posing health risks. Therefore, controlling these contaminants is vital in manufacturing to ensure the final product meets safety standards. Only drugs that pass stringent endotoxin testing are safe for therapeutic use, safeguarding patients and research participants.

Mechanism of Endotoxin Reaction with Horseshoe Crab Reagent

The horseshoe crab reagent is a sensitive in vitro assay composed of lysate extracted from the destabilized cells of horseshoe crab blood, which reacts to even minute quantities of bacterial endotoxin by forming a specific gel. This reaction's rate correlates with the endotoxin concentration. The reagent contains C factor, B factor, coagulogen, and coagulation protease. Under suitable conditions of temperature and pH, endotoxins activate the C factor, which in turn activates the B factor, leading to a cascade of enzymatic reactions that result in gel formation.

Endotoxin Testing Precautions

• When diluting endotoxins, avoid using syringes; use endotoxin-free dilution tubes instead. All consumables should undergo endotoxin-free treatment.
• Endotoxin testing water should contain <0.015 EU/ml of bacterial endotoxins, typically utilizing water supplied by manufacturers specifically for bacterial endotoxin testing.
• During the mixing of the test sample and horseshoe crab reagent, as well as during the dissolution of the reagent, avoid vigorous shaking to prevent bubbles that could affect experimental accuracy.
• While conducting interference and sensitivity tests with horseshoe crab reagent, control experiments must be performed concurrently. Only when control results are valid can those of the test sample be considered reliable.
• Due to the irreversible nature of the clotting process in gel clot tests, avoid vigorous agitation during experimentation and result observation to prevent false negative results.
