Description | Specificity: K39 reacts exclusively with glial fibrillary acidic protein which is present in astrocytes in the central nervous system and Schwann cells. GFAP (55 kD) is selectively loCated in astrocytes and represents the major constituent of astrocytic intermediate filaments. GFAP expression levels are highly variable during development of the central nervous system. In adults, GFAP levels increase as a result of the prolifeRation of astrocytes that occurs in a response to a variety of physical, chemical and etiological insults, including Alzheimer's disease, epilepsy and multiple sclerosis. In the peripheral nervous system GFAP is expressed by Schwann cells. Upon differentiation, myelin forming Schwann cells down-regulate GFAP, whereas in |
