  • Assay methods involving ouabain
    Patent number: 5164296
    Abstract: Methods for diagnosing pre-hypertension, hypertension, congestive cardiomyopathy, renal failure, salt-sensitivity and adenomas and endocrine cell hyperplasias are disclosed. Also disclosed are methods for monitoring hypertension therapy, congestive cardiomyopathy therapy, renal failure therapy and adenoma and endocrine call hyperplasia therapy. These methods involve using an antibody having binding specificity to ouabain to immunologically measure the level of human ouabain in body fluid or tissue of a subject. Additionally, methods for treating a hypertensive subject by inducing passive or active immunity to human ouabain in the subject are disclosed, along with an antibody having binding specificity for ouabain.
