Used in immunology and inflammation research to quantitatively measure leukotriene B4 levels in biological samples such as serum, plasma, or cell culture supernatants from rat models. This kit enables researchers to study the role of LTB4 in inflammatory diseases, immune responses, and drug development by providing a sensitive and specific method to assess LTB4 concentration. It is commonly applied in studies related to arthritis, asthma, atherosclerosis, and other conditions involving neutrophil activation and chemotaxis. The assay supports high-throughput analysis and is essential for evaluating the efficacy of anti-inflammatory compounds in preclinical research.
