Used in biomedical research to quantify leukotriene E4 levels in biological samples such as plasma, serum, or cell culture supernatants. It helps investigate inflammatory processes, particularly in asthma, allergic reactions, and other respiratory diseases. The kit enables researchers to monitor immune responses and evaluate the effectiveness of anti-inflammatory drugs in experimental models. Due to its specificity, it supports studies focused on eicosanoid pathways and cysteinyl leukotriene metabolism.
