GFR α 1 (extracellular) Blocking Peptide (#BLP-NT021) is the original antigen used for immunization during Anti-GFR alpha 1 (extracellular) Antibody (#ANT-021) generation. The blocking peptide binds and ‘blocks’ Anti-GFR α 1 (extracellular) primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.

- Expression of GFRA1 in rat neocortexImmunohistochemical staining of immersion-fixed, free floating rat brain frozen sections using Anti-GFR alpha 1 (extracellular) Antibody (#ANT-021), (1:100). A. GFRA1 (green) is visualized in neocortex neurons. B. Neurons expressing γ-amino butyric acid (GABA) are labeled with parvalbumin (red). C. Merge of the two images demonstrates partial colocalization (arrows).
