Immunoprecipitation of GFAP protein from mouse brain tissue extracts. Lane 1 is 10% input, lane 2 is Mouse (E5Y6Q) mAb IgG2a Isotype Control #61656, and lane 3 is GFAP (E6N9L) Mouse mAb. Western blot analysis was performed GFAP (E6N9L) Mouse mAb.
Confocal immunofluorescent analysis of mouse Tg2576 brain, which overexpresses mutant human APP695. Sections were labeled with GFAP (E6N9L) Mouse mAb (green, mouse IgG2a), β-Amyloid (D3D2N) Mouse mAb #15126 (red, mouse IgG1), and HS1 (D5A9) XP® Rabbit mAb (Rodent Specific) #3892 (magenta, rabbit IgG). Samples were mounted in ProLong® Gold Antifade Reagent with DAPI #8961 (blue).
The cytoskeleton consists of three types of cytosolic fibers: microfilaments (actin filaments), intermediate filaments, and microtubules. Major types of intermediate filaments are specifically expressed in particular cell types: cytokeratins in epithelial cells, glial fibrillary acidic protein (GFAP) in glial cells, desmin in skeletal, visceral, and certain vascular smooth muscle cells, vimentin in cells of mesenchymal origin, and neurofilaments in neurons. GFAP and vimentin form intermediate filaments in astroglial cells and modulate their motility and shape (1). In particular, vimentin filaments are present at early developmental stages, while GFAP filaments are characteristic of differentiated and mature brain astrocytes. Thus, GFAP is commonly used as a marker for intracranial and intraspinal tumors arising from astrocytes (2). In addition, GFAP intermediate filaments are also present in nonmyelin-forming Schwann cells in the peripheral nervous system (3).
