Used in biomedical research to quantify levels of glucocorticoid receptor alpha in rat tissue samples or cell lysates. Enables researchers to study the regulation of glucocorticoid signaling pathways involved in inflammation, immune response, stress, and metabolism. Commonly applied in pharmacological studies to assess the effects of drugs or experimental compounds on receptor expression. Also useful in endocrine research to investigate hormonal regulation and receptor dynamics under various physiological or pathological conditions. Provides a reliable, high-throughput method for measuring GR-α protein concentration with high sensitivity and specificity.
