Used in biomedical research to quantify levels of the glucocorticoid receptor beta (GR-β) in rat tissue samples or cell lysates. This assay helps investigate the role of GR-β in inflammatory diseases, stress responses, and hormonal regulation. It is particularly useful in studies exploring glucocorticoid resistance, where elevated GR-β expression may interfere with the anti-inflammatory actions of glucocorticoids. Researchers use this kit to evaluate drug efficacy, immune responses, and endocrine disruptions in rat models, supporting preclinical research in immunology, pharmacology, and molecular biology.
