Product Information
Product Description
This Cell Signaling Technology® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as GFAP (E4L7M) XP® Rabbit mAb #80788.
Product Usage Information
| Application | Dilution |
|---|---|
| Immunofluorescence (Frozen) | 1:50 - 1:200 |
Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
Protocol
Specificity / Sensitivity
GFAP (E4L7M) XP® Mouse Chimeric mAb recognizes endogenous levels of total GFAP protein.
Species Reactivity:
Human, Mouse, Rat, Monkey
Source / Purification
This recombinant chimeric antibody is engineered from GFAP (E4L7M) XP® Rabbit mAb #80788 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a mouse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.
The parent antibody, GFAP (E4L7M) XP® Rabbit mAb #80788, is produced by immunizing animals with recombinant protein specific to the human GFAP protein.

Background
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).
