Used to measure 5-lipoxygenase (5-LO/LOX) enzyme activity in human biological samples such as blood, plasma, or cell lysates. This kit is widely applied in research settings to study inflammatory processes, as 5-LO plays a key role in the production of leukotrienes—mediators involved in asthma, arthritis, and other inflammatory diseases. It enables researchers to evaluate the effectiveness of anti-inflammatory drugs by monitoring changes in 5-LO activity. Commonly used in pharmaceutical development, immunology research, and biomarker discovery.
