Immunohistochemical staining of GFAP-positive radial glial cells in the periventricular zone of an e16 mouse brain.  Section was a vibratome, thick section (20 um) using a lightly-fixed (2% paraformaldehyde) mouse brain.  1˚ antibody (GFAP) was used at 1:500 dilution; 2˚ antibody (HRP-goat anti-chicken IgY) was used at 1:500 dilution.

Product Details | ↓ Citations


This antipeptide IgY antibody was generated in chickens against a C-terminal sequence shared between the mouse (NP_032109) and rat (NP_05889.1) gene products. It has been validated with human, mouse and rat tissues.


Volume: 200 µL

Concentration: 2 mg/mL (based on absorbance at 280 nm)

Clonality: Polyclonal

Host Species: Chicken

Species Reactivity: Human, Mouse, Rat

Applications: ICC, IHC, WB

Protein Name / Synonyms: Glial fibrillary acidic protein (GFAP)

Target Description: Human Glial Fibrillary Acidic Protein (GFAP) is a 49,749 dalton protein (432 amino acids) expressed by astrocytes of the central nervous system. GFAP is an intermediate filament protein and acts as an intra-cellular structural component of the astrocytic cytoskeleton. During embryonic and fetal life, GFAP is also expressed by radial glial cells of the CNS. Rare mutations of the GFAP gene in humans result in Alexander’s disease, one of the leukodystrophies.

Gene ID: GFAP

Antibody Registry ID (RRID): AB_2313547

Physical State: Liquid

Buffer: Phosphate-buffered (10 mM) isotonic (0.9%, w/v) saline ("PBS" pH 7.2) with bovine serum albumin (BSA, 0.5%) added to prevent absorption to the plastic and sodium azide (0.02%, w/v) added as a preservative

Production Notes: Chickens were immunized with recombinant GFAP (expressed in bacteria). After repeated injections, immune eggs were collected, the IgY fractions were purified from the yolks, and the IgY concentration adjusted to 20 mg/mL. This preparation was then diluted 1:10 with PBS containing bovine serum albumin as a carrier. Finally, the antibody preparation was filter-sterilized.

Validation and Application Notes

Molecular Weight: 50 kDa

Western Blot Dilution Range: 1:1000-1:2000

IHC Dilution Range: 1:500-1:1000

Quality Control

Quality assurance analysis was performed using immunohistochemistry (at a dilution of 1:5000) using fluorescein-labeled goat anti-chicken IgY (1:500 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.

Storage

Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least 12 months (provided they remain sterile). Do not freeze these antibodies unless you want to store them for longer periods of time. Note, however, that each time an antibody preparation is frozen, about half of its binding activity is lost.
