Used in neuroscience and metabolic disease research to quantify GFRAL protein levels in biological samples. Helps investigate the role of GFRAL in appetite regulation and energy homeostasis, particularly in studies related to obesity and diabetes. Enables researchers to measure changes in GFRAL expression in response to therapeutic interventions or hormonal signals such as glial cell line-derived neurotrophic factor (GDNF) family ligands. Supports biomarker discovery and validation in preclinical models.
