1. Since applications vary, each investigator should titrate the reagent to obtain optimal results. 2. Please refer to us for technical protocols. 3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
GFAP
Reactivity: Human
WB, IHC, IF
Host: Rabbit
Monoclonal
unconjugated
Application Notes
Applications include indirect immunofluorescence of tissue-cultured cells, immunohistochemical staining of formalin-fixed paraffin-embedded brain tissue sections (10-15 µg/ml), and western blot analysis (1-2 µg/ml). Rat brain is suggested as a positive control. Antibodies-online offers these GFAP specific antibodies separately: clone 4A11 (ABIN967499), clone 1B4 (ABIN967500) and clone 2E1 (ABIN967501).
This product contains Sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

GFAP (Glial Fibrillary Acid Protein) is the major protein of glial filaments in differentiated astrocytes. We offer a panel of monoclonal antibodies (4A11, 1B4, 2E1) that specifically recognize GFAP. They do not cross-react with other intermediate filaments such as vimentin, neurofilament proteins, desmin, keratin, neurotubules or microfilaments. Bovine spinal cord homogenate was used as immunogen for these clones. Clones 4A11, 1B4, and 2E1 have broad species reactivity, recognizing GFAP in brain homogenates from human, mouse, rat, bovine, ovine, canine, porcine, rabbit, guinea pig and chicken. The cocktail preparation was made by combining all three antibodies in equal concentrations. The antibodies are routinely tested by immunohistochemical staining of formalin-fixed, paraffin-embedded brain tissue samples, which were subjected to pretreatment with citrate or tissue unmasking fluid (see figure).
