Used in biomedical research to quantify levels of the human glucocorticoid receptor alpha (GR-α) in cell lysates, tissue extracts, and biological fluids. Enables researchers to study GR-α expression and regulation in conditions involving stress response, inflammation, immune function, and metabolic disorders. Commonly applied in drug development to assess the impact of glucocorticoids and other therapeutics on receptor levels. Supports investigations into glucocorticoid resistance seen in diseases like asthma, depression, and certain cancers. Provides a reliable, sensitive, and specific method for high-throughput screening in laboratory settings.
