Used in immunology and inflammation research to quantitatively measure Leukotriene B4 levels in biological samples such as serum, plasma, and cell culture supernatants. Enables researchers to study the role of LTB4 in inflammatory diseases including arthritis, asthma, and atherosclerosis. Commonly applied in drug development to assess the efficacy of anti-inflammatory compounds by monitoring changes in LTB4 production. Supports investigation into immune cell function, particularly neutrophil chemotaxis and activation. Suitable for use in preclinical studies and biomarker discovery.
