Full length native protein (purified) corresponding to GFAP.
Our Abpromise guarantee covers the use of ab7260 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-FoFr||1/5000. See Abreview.|
|WB||1/10000. Detects a band of approximately 55,48 kDa.
This lower 48kDa band is thought to be a degradation product.
|IHC-P||1/5000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
ab7260 staining GFAP in cells from mouse brain tissue sections by ICC/IF (Immunocytochemistry/immunofluorescence). 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. ab96883 was used as the secondary antibody at a dilution of 1/200.
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 labelled.

IHC - Wholemount of rat retina tissue labelling GFAP (red) with ab7260. Sample was incubated with primary antibody (1/100) for 18 hours at 4°C. A Phycoerythrin-conjugated goat anti-rabbit IgG monoclonal (1/1000) was used as the secondary antibody.
ab7260 at 1/10000 dilution staining Mouse cortical astrocytes by Immunocytochemistry. The cells were permeabilized with Triton/HEPES buffer prior to primary application. The antibody was incubated with the cells for 18 hours and then bound antibody was detected with an Alexa Fluor ® 488 conjugated goat anti-rabbit antibody.

Immunohistochemical analysis 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.
ab7260 staining rat brain tissue sections by IHC-P. Sections were fixed in formaldehyde and bocoked with a commercialy available blocking agent prior to incubating with ab7260, diluted 1/5000 for 20 hours at 4°C. A HRP conjugated mouse polyclonal (universal HRP polymer detection) antibody was used as the secondary.
Immunohistochemical analysis of formaldehyde-fixed paraffin-embedded canine neuronal tissue sections, labelling GFAP with ab7260 at a dilution of 1/1000 incubated for 90 minutes at 25°C. Antigen retrival was with 10mM citrate pH6.0 (heat mediated). Blocking was with 10% serum incubated for 30 minutes at 25°C. Secondary was a Goat anti-rabbit polyclonal Texas Red® conjugate at 1/200.
ab7260 staining rat pup cortical preps by ICC/IF. The preps were grown for 14 days in culture and plated onto coverslips. The preps were acid/alcohol fixed and blocked prior to incubation with ab7260. Bound antibody was detected using an Alexa Fluor ®488 conjugated goat polyclonal antibody. Nuclei were visualised using DAPI.
Western blot of whole rat cerebellum homogenate stained with ab7260 at dilution of 1:100,000. A prominent band running with an apparent SDS-PAGE molecular weight of ~55kDa corresponds to rodent GFAP. A lower band at ~48kDa is derived from the GFAP molecule.
