Used in neuroscience and metabolic research to quantify levels of Orexin-A (also known as hypocretin-1) in biological samples such as cerebrospinal fluid, plasma, or tissue extracts. This ELISA research kit enables researchers to study the role of Orexin-A in regulating sleep-wake cycles, particularly in narcolepsy and other sleep disorders. It is also applied in studies related to appetite control, energy balance, and addiction due to Orexin-A’s involvement in reward pathways and feeding behavior. The assay provides a sensitive and specific method for detecting changes in Orexin-A concentration under experimental or pathological conditions, supporting both clinical research and drug development.
