MICROTUBULE-ASSOCIATED PROTEIN 2, abbreviated MAP2,[1] is a common immunostain used in neuropathology and pulmonary pathology. It's expression is associated with neuronal, glial or neuroendocrine differentiation
Positive
- CNS cortex, esp. neurons. [2]
- Oligodendroglioma, predominantly perinuclear [3]
- Ganglioglioma [4]
- Astrocytoma / Glioblastoma [5]
- Neurocytoma / Medulloblastoma [6]
- Dysembryoplastic neuroepithelial tumour [7]
- Small cell lung carcinoma [8]
- Carcinoid tumour [9]
- Merkel cell carcinoma [10]
