Anti-Glial Fibrillary Acidic Protein (Rabbit) antibody is suitable for use in Western Blotting and IF. Anti-Glial Fibrillary Acidic Protein antibodies are specific for the ~50kDa GFAP protein. A lower band at ~45kDa is a proteolytic fragment derived from the GFAP molecule. Specific conditions for reactivity should be optimized by the end user.
