Used in biomedical research to quantitatively measure ADRA1A receptor levels in human tissue samples or cell lysates. Helps in studying the role of alpha-1A adrenergic receptors in cardiovascular function, smooth muscle contraction, and neurological processes. Commonly applied in drug development and pharmacological studies targeting hypertension, benign prostatic hyperplasia, and central nervous system disorders. Enables researchers to assess receptor expression changes in response to therapeutic agents or disease states.
