ABSTRACT:
Interfering proteins are precipitated and digoxin extracted in a fluorescence polarization immunoassay for digoxin with a protein precipitating reagent. The reagent contains about 3 to 4% 5-sulfosalicyclic acid in an aqueous solution including about 40 to 60% of a straight or branch chained organic alcohol having from 1 to 4 carbon atoms.
