Neuron-specific enolase (NSE) is a highly specific marker used extensively in neuropathology and oncology to identify neurons and neuroendocrine cells in various tissue specimens. It's also valuable in identifying tumors that originate from or resemble nervous system or neuroendocrine tissues. 

The NSE antibody is a powerful tool for delineating neural and neuroendocrine pathology in both clinical and research settings. It provides crucial diagnostic insights, particularly in the context of tumors and neuronal damage.
