Applications

Recommended Concentration
Sample
Flow Cytometry
0.25 µg/106 cells
See below
Blockade of Receptor-ligand Interaction
In a functional ELISA binding assay, 100-800 ng/mL of this antibody will block 50% of the binding of 10 ng/mL of Recombinant Human GDF-15 (Catalog # 9279-GD) to immobilized Recombinant Human GFR alpha -like Fc Chimera (Catalog # 9697-GR) coated at 0.1 μg/mL (100 μL/well). At 10 μg/mL, this antibody will block >90% of the binding.
 
CyTOF-ready
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
 

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.

Background: GFR alpha-like

GFR alpha -like (GDNF receptor-alpha-like) is a distant member of the GDNFR family of proteins (1). Mature human GFR alpha-like is a 376 amino acid (aa) type I transmembrane protein. It contains a 333 aa extracellular domain, a 20 aa transmembrane domain and a 23 aa cytoplasmic domain. Over the extracellular domain, human GFRAL shares 72% and 71%  identity with mouse and rat GFRAL respectively. It is expressed on both fetal and adult hindbrain neurons of the CNS (3), and would appear to function as an anti-apoptotic molecule during neuronal stress. GFRAL is a functional receptor for GDF-15, facilitating weight-loss functions of the protein through c-Ret downstream signaling (2-4). GFRAL and GDF-15 signaling is implicated in diet-based obesity and insulin resistance (2-4).
