Used in neuroscience and clinical research to quantify levels of neuron-specific enolase (NSE), a biomarker associated with neuronal damage and certain neuroendocrine tumors. The kit enables detection and measurement of NSE in biological samples such as serum, plasma, or cerebrospinal fluid. It is commonly applied in studies related to traumatic brain injury, stroke, hypoxic-ischemic encephalopathy, and small cell lung cancer. The ELISA format allows for high sensitivity and specificity, making it suitable for monitoring disease progression, evaluating treatment efficacy, and supporting diagnostic research in neurological and oncological fields.
