Used in neuroscience and metabolic research to quantify orexin B (also known as hypocretin-2) levels in biological samples such as cerebrospinal fluid, plasma, or tissue extracts. This ELISA kit enables researchers to study the role of orexin B in regulating sleep-wake cycles, appetite, and energy homeostasis. It is particularly valuable in investigations related to narcolepsy, insomnia, obesity, and other disorders involving the orexin signaling pathway. The assay provides a sensitive and specific method for detecting changes in orexin B concentration, supporting both basic research and preclinical studies.
