Used in biomedical research to measure cysteine leukotriene levels in biological samples such as blood, plasma, or cell culture supernatants. These kits are essential for studying inflammatory processes, particularly in asthma, allergic rhinitis, and other allergic or inflammatory diseases. By quantifying CysLTs, researchers can assess immune cell activity, evaluate the effectiveness of anti-inflammatory drugs, and investigate the role of leukotrienes in disease mechanisms. Commonly used in clinical labs and pharmaceutical research for high-throughput screening and biomarker validation.
