Preparation And Storage
Recommended Assay Procedures
Pharmingen offers additional GFAP specific antibodies: clone 1B4 (Cat. No. 556328); 4A11 (Cat. No. 556327); clones 1B4, 4A11, 2E1 combined and available as a "cocktail" (Cat. No. 556330). Applications include immunohistochemical staining of formalin-fixed paraffin-embedded brain tissue sections (5-25 µg/ml); and western blot analysis (1-2 µg/ml). Rat brain is suggested as a positive control.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

Companion Products
GFAP (Glial Fibrillary Acid Protein) is the major protein of glial filaments in differentiated astrocytes. BD PharMingen offers 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 clone 2E1. This antibody has broad species reactivity. It recognizes GFAP in brain homogenates from human, mouse, rat, cow, sheep, dog, pig, rabbit, guinea pig and chicken. 2E1 is particularly useful for identifying GFAP in immunohistochemistry of frozen and formalin-fixed, paraffin-embedded brain tissue sections. Additional applications include western blot analysis and indirect immunofluorescence of tissue-cultured cells.
