Abstract:
Described herein are deposited hybridoma cell lines and the monoclonal antibodies produced by these hybridomas, and antigen binding fragments thereof. These monoclonal antibodies and antigen binding fragments specifically bind marinobufagenin. The disclosure also encompasses the use of these monoclonal antibodies or antigen binding fragments in a method for detecting the presence of marinobufagenin in a biological sample. Also provided are methods for the use of these monoclonal antibodies or antigen binding fragments as prophylactic, therapeutic, and diagnostic agents for the detection, inhibition and treatment of a cardiovascular disease, for example, essential hypertension, hypertension associated with preeclampsia, eclampsia, or renal failure, or myocardial fibrosis in a subject.
