To use this antibody with tissue clearing, use Tissue Clearing Kit ab243298. For 1 mm brain sections, we recommend a starting dilution of 1:1000, and also using Goat Anti-Rabbit IgG H&L AlexaFluor488 (ab150077) at a dilution of 1:400.

Increases in GFAP after demyelinating injury are greater in the spinal cord compared to brain

Photomicrographs show immunoreactivity for GFAP or ALDH1L1 in (A) the corpus callosum, or (B) the dorsal column white matter of adult mice at base line, and at 14 d after microinjection of the demyelinating agent lysolecithin. Histograms show the percent area of GFAP immunofluorescence, and expression of GFAP/ALDH1L1+ astrocyte, was significantly greater in the spinal cord compared to the corpus callosum 14d post-lysolecithin lesion.

GFAP was detected using ab7260.

Apoptosis after 2 Gy ionising radiation (IR) only arises in the 2 subdomains containing progenitor cells

Images showing GFAP+ cells (magenta), Ki67+ cells (red), terminal deoxynucleotidyl transferase-mediated dUTP nick end-labelling (TUNEL)+ cells (green), and DAPI staining (grey) within the 4 subdomains. Separate colour channels are given in S1E Fig. Apoptosis is only observed in the dorsolateral and ventral subdomains.

GFAP is detected in frozen sections of mouse brain using ab7260 at 1/500 dilution.

Immunohistochemistical detection of GFAP antibody - Astrocyte Marker (ab7260) on formaldehyde-fixed paraffin-embedded monkey brain sections.

Antigen retrieval step: Heat mediated.  Buffer Used: Citric acid pH6. Permeabilization: None. Blocking step: 1% BSA for 10 mins @ 21°C. Primary antibody incubated at 1/2000 for 2 hours @ 21°C in TBS/BSA/azide. Secondary antibody: anti rabbit IgG Conjugated to biotin  (1/200). Marmoset brain: astrocytes are clearly and strongly labeled.

Immunocytochemistry/Immunofluorescence of mixed neuron-glial cultures labelling rabbit GFAP (red channel) and chicken vimentin CPCA-Vim (green channel). The fibroblastic cells contain only vimentin and so are green, while astrocytes contain either vimentin and GFAP, so appearing golden, or predominantly GFAP, in which case they appear red. Blue is nuclear DNA stain.

IHC image of GFAP staining in a formalin fixed, paraffin embedded normal mouse brain tissue section, performed on a Leica Bond™ system using the standard protocol B.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab7260 at 1/2000 dilution for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with hematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Rats were transcardially perfused with 4% PFA. The tissue was post fixed 1 hour in 4% PFA and then 30% sucrose for three days. 20µm sections were cryostat cut. The primary antibody was incubated with the tissue sections for 18 hours. Bound antibody was detected using an Alexa Fluor ^® 488 conjugated goat anti-rabbit polyclonal.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab7260 at 1/2000 dilution for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with hematoxylin and mounted with DPX.

Cells were fixed with paraformaldehyde, permeabilized with 0.1% Tween 20 in PBS and blocked with 1% BSA for 40 minutes at 25°C. Samples were incubated with primary antibody (1/1200 in TBS) for 24 hours at 4°C. Goat Anti-Rabbit IgG H&L (DyLight^® 488) (ab96883) was used as the secondary antibody at a dilution of 1/200.
