Used in neuroscience and pharmacology research to quantify mouse orphanin FQ (nociceptin) levels in biological samples such as brain tissue, cerebrospinal fluid, or cell culture supernatants. The ELISA kit enables researchers to study the role of the orphanin FQ/NOP receptor system in pain modulation, stress responses, anxiety, feeding behavior, and drug dependence. It is a valuable tool for investigating neurobiological pathways in mouse models, supporting studies on potential therapeutic targets for mood disorders, addiction, and chronic pain. The assay provides high sensitivity and specificity, allowing accurate measurement of peptide concentration in small sample volumes.
