Used in neuroscience and biomedical research to quantify levels of METRNL protein in mouse brain tissue, particularly in the striatum region. Helps investigate the role of METRNL in neuroinflammation, neurodegenerative diseases, and neuroprotective mechanisms. Supports studies on metabolic regulation, mood disorders, and exercise-induced brain changes due to METRNL's involvement in neuro-immune crosstalk. The ELISA kit format allows for high sensitivity and specificity in detecting protein expression changes across experimental conditions.
