Anti-GFAP antibody (ab4674)

ab4674 staining GFAP in primary hippocampal rat neurons/glia, (obtained from Neuromics, cat. no. PC35101), DIV14. The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% PBS-Tween for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab4674 at 1µg/ml and ab87122, Rabbit Poly to Mouse Fructose-bisphosphate aldolase C (No Modifications). Cells were then incubated with ab150176, Goat polyclonal Secondary Antibody to Chicken IgY - H&L (Alexa Fluor^® 594), pre-adsorbed at 1/1000 dilution (shown in red) and ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor^® 488), pre-adsorbed at 1/1000 dilution (shown in pseudocolour green). Nuclear DNA was labelled with DAPI (shown in blue).

Also suitable in cells fixed with 4% paraformaldehyde (10 min).

Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

GFAP antibody ab4674 was used with Tissue Clearing Kit ab243298 to penetrate, stain and clear a 500 μm section of rat brain.

10x and 63x z-stack images of the CA1 hippocampal region for each treatment are shown, with NeuN staining in green and GFAP staining in red.

Two month-old wild-type mice were placed on either control (n = 10) or inhibitor diet (PLX3397, provided at 290 mg/kg chow; n = 14) for 21 d, causing the elimination of approximately 99% of microglia brain-wide.

Fluorescent immunolabeling of the microglia followed a standard indirect technique (primary antibody followed by fluorescent secondary antibody). Brain tissue (sliced at 40 μm) was stained using the anti-ionized calcium-binding adapter molecule 1 (IBA1, polyclonal, rabbit) antibody (1:1000; Wako, Cat. #019–19741), mounted on slides, and coverslipped using Dapi Fluoromount-G (SouthernBiotech). Half brain images were obtained by stitching using a Zeiss AxioImager M2 upright microscope and Stereo Investigator software package from MicroBrightField. In addition, tissue was stained with anti-hexaribonucleotide binding protein-3 (NeuN, monoclonal, mouse) antibody (1:1000; Millipore; Cat. #MAB377) to label neurons and anti-glial fibrillary acidic protein (GFAP, polyclonal, chicken) antibody (1:500; Abcam; Cat. #ab4674) to label astrocytes, and 10x and 63x z-stack images obtained for each treatment using confocal microscopy.

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.
