Anti-Glial Fibrillary Acidic Protein (Chicken) antibody is suitable for use in Western Blotting and IF. Specific conditions for reactivity should be optimized by the end user. Expect a band of approximately 50 kDa in size corresponding to the GFAP proteins in the appropriate cell lysate or extract. A lower band at ~45kDa is a proteolytic fragment derived from the GFAP molecule.
