  • Blockade of Receptor-ligand Interaction
    In a functional ELISA, 1-3 µg/mL of this antibody will block 50% of the binding of 2 ng/mL of Recombinant Human GDNF (Catalog # 212-GD) to immobilized Recombinant Mouse GFR alpha -2 Fc Chimera (Catalog # 429-FR) coated at 1 µg/mL (100 µL/well). At 15 μg/mL, this antibody will block >90% of the binding.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Immunohistochemistry
GFR alpha ‑2/GDNF R alpha ‑2 in Mouse Dorsal Root Ganglion.
GFR alpha ‑2/GDNF R alpha ‑2 was detected in perfusion fixed frozen sections of mouse dorsal root ganglion using Goat Anti-Human/Mouse GFR alpha ‑2/GDNF R alpha ‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF429) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membrane of sensory neurons. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: GFR alpha-2/GDNF R alpha-2

Glial cell line-derived growth factor (GDNF), neurturin (NTN), persephin (PSP) and artemin, distant members of the TGF-beta  superfamily, are neurotrophic factors for a variety of neuronal populations in the central and peripheral nervous systems. The bioactivities of GDNF and NTN are mediated through a receptor complex composed of the non ligand-binding signaling subunit (c-Ret receptor tyrosine kinase) and either of two ligand binding subunits, GDNF receptor alpha -1 (GFR alpha -1, also known as Trn R1) or GFR alpha -2 (also known as Trn R2). GFR alpha -1 and -2 are members of a family of at least four cysteine-rich glycosyl-phosphatidylinositol (GPI)-linked cell surface proteins that share conserved placements of many of their cysteine residues. Binding of GDNF or NTN to membrane-associated GFR alpha -1 or GFR alpha -2 initiates the association with and activation of the Ret tyrosine kinase.

Mouse GFR alpha -2 cDNA encodes a 463 amino acid (aa) residue protein with a putative N-terminal 21 aa residue hydrophobic signal peptide. Like other GPI-linked proteins, rat GFR alpha -2 has a C-terminal hydrophobic region which is preceded by a 3 aa residue (SGS) GPI-binding site. Human GFR alpha -2 shares 96.5% amino acid identity with mouse GFR alpha -2. The expression of the various GFR alpha s are differentially regulated in the central and peripheral nervous system, suggesting complementary roles for the GFR alpha s in mediating the activities of the GDNF family of neurotrophic factors.
