title: Production and characterization of antibodies to ouabain.
abstract: Two monoclonal antibodies (249F8 and 278A9) to ouabain were produced by somatic cell fusion. They reacted in dose-dependent manners with ouabain and digoxin. These antibodies were supposed to recognize the partial structure important for cardiac compounds to show their pharmacological activity, Na+, K(+)-ATPase inhibition in a competitive mode against K+. These monoclonal antibodies may be useful for the immunochemical isolation, the structural elucidation, and the quantitative measurement of putative endogenous digoxin-like factors.
