Anti-GFAP antibody (ab4674)

Immunofluorescent analysis of a section of mouse hippocampus stained with ab4674 at a 1:5,000 dilution in green.

Costained with a rabbit pAb to FOX3/NeuN dilution 1:5,000, in red. The blue is DAPI staining of nuclear DNA. Following transcardial perfusion with 4% paraformaldehyde, mouse brain was post fixed for 24 hours, cut to 45 μM, and free-floating sections were stained. The GFAP antibody stains a network of astroglial cells while the Fox3/NeuN antibody stains the nuclei and proximal perikarya of neurons.

The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH 6). The section was incubated with ab4674 at 1/1000 dilution for 15 minutes at room temperature. A goat anti-chicken biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. The section was counterstained with haematoxylin and mounted with DPX.

ab4674 staining GFAP in mouse hippocampus tissue section by Immunohistochemistry (PFA perfusion fixed frozen sections).

Tissue samples were fixed by perfusion with 4% PFA and blocked with 10% serum for 30 minutes at 25°C. The sample was incubated with primary antibody (1/500) for 16 hours at 25°C in 10% NGS in PBS + 0.1% TX100. An Alexa Fluor^®488-conjugated Goat polyclonal to chicken IgG was used as secondary antibody at 1/400 dilution. Staining was intensified with 2-3 minutes of retrieval with trypsin at room temperature.

ab4674 staining GFAP in human brain cells by Flow Cytometry.

Cells were grown in stem cell media, RHB-A, and collected using 0.05% trypsin + trypsin inhibitor. Cells were fixed in 80% Acetone for 5-10 minutes at -20°C. The sample was incubated with the primary antibody (1/100 in 10% FCS in PBS) for 20 minutes at 25°C. ab46969 a goat anti-chicken IgY FITC (1/100) was used as the secondary antibody

ab4674 detecting recombinant GFAP by direct ELISA.

Mouse recombinant GFAP protein was coated onto a microplate in carbonate coating buffer pH 9.6 for 1 hour at 37°C. Plate was blocked with 3% BSA for 1 hour at 37°C and incubated with the primary antibody (1/5000 in PBS + 1% Tween-20) for 1 hour at 37°C. An undiluted alkaline phosphatase Goat anti-chicken IgG polyclonal was used as the secondary antibody.
