Human GFRA3 ELISA Kit (HUFI04131)

Built around the GFRα3 receptor that preferentially partners with the RET tyrosine kinase to mediate artemin (ARTN) neurotrophic signaling, this quantitative immunoassay from Assay Genie measures human GFRα3 protein levels in research specimens. GFRα3 is a glycosylphosphatidylinositol-anchored co-receptor most often studied in dorsal root ganglion sensory neurons, sympathetic neuron populations, and select tumor contexts, where it contributes to neuronal survival, neurite outgrowth, and nociceptive function. Scientists investigating GDNF-family ligand pathways, peripheral nervous system development, or cancer cell signaling can use the kit to track GFRα3 abundance across experimental conditions.

Supplied as a complete microplate-format kit with reagents sufficient for 96 assays, the workflow is intended for in vitro research use only and accepts human serum-based or plasma-derived samples. Detection relies on an absorbance-based readout readable on standard plate readers, and refrigerated storage between uses preserves reagent activity. The product complements molecular studies of neurotrophic factor signaling, including investigations into how GFRα3–ARTN–RET complexes shape sensory neuron biology and how circulating GFRα3 may be quantified in translational research cohorts.
