Abstract
The invention provides methods for obtaining substantially purified high and low molecular weight Na-K-ATPase inhibitor compounds having natriuretic and vasoconstrictive activity, antibodies reactive with the compounds and methods for their use in diagnostic and therapeutic applications to detect elevated or decreased amounts of the compounds in subjects having diseases associated with the presence or deficiency of these natriuretic compounds.
Claims1
A substantially pure isolated low molecular weight plasma inhibitor of Na-K-ATPase occurring in human plasma and characterized by having vasoconstrictive and natriuretic activity and displacing ouabain from its receptor and lacking reactivity with anti-digoxin antibody, said inhibitor having a molecular weight of less than 500 peptide.
