ab62479 was affinity purified from rabbit antiserum by affinity chromatography using epitope specific phosphopeptide. The antibody against non phosphopeptide was removed by chromatography using non phosphopeptide corresponding to the phosphorylation site.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/50 - 1/100.

GFAP, a class-III intermediate filament, is a cell-specific marker that, during the development of the central nervous system, distinguishes astrocytes from other glial cells.
Expressed in cells lacking fibronectin.
Involvement in disease
Defects in GFAP are a cause of Alexander disease (ALEXD) [MIM:203450]. Alexander disease is a rare disorder of the central nervous system. It is a progressive leukoencephalopathy whose hallmark is the widespread accumulation of Rosenthal fibers which are cytoplasmic inclusions in astrocytes. The most common form affects infants and young children, and is characterized by progressive failure of central myelination, usually leading to death usually within the first decade. Infants with Alexander disease develop a leukoencephalopathy with macrocephaly, seizures, and psychomotor retardation. Patients with juvenile or adult forms typically experience ataxia, bulbar signs and spasticity, and a more slowly progressive course.
Belongs to the intermediate filament family.
Phosphorylated by PKN1.
Cytoplasm. Associated with intermediate filaments.

ab62479 staining GFAP (phospho S38) in mouse brain tissue section by Immunohistochemistry (Frozen sections). Tissue samples were fixed with paraformaldehyde and blocking with a dilution buffer containing 2% Block Ace, 0.05% Triton X-100 and PBS was performed at 250C for 1 hour. The sample was incubated with primary antibody (1/100) at 40C for 12 hours. A Cyt3 ® -conjugated donkey polyclonal to rabbit IgG was used as secondary antibody at 1/500 dilution.
