Used in immunological research to quantify mouse Retinoid-related orphan receptor gamma (RORγ) ligand Retinoid acid receptor-related orphan receptor alpha (RORα) modulator, commonly referred to as RvE3, in biological samples such as serum, plasma, and tissue homogenates. The kit enables precise measurement of RvE3 levels in mouse models, supporting studies on inflammation resolution, immune regulation, and metabolic disorders. It is widely applied in preclinical research to evaluate the role of specialized pro-resolving mediators in controlling inflammatory responses and in the development of anti-inflammatory therapeutics. The assay is suitable for high-throughput screening and provides a reliable tool for investigating the RvE3 signaling pathway in disease models including arthritis, colitis, and sepsis.
