Heterogeneous immunoassay for digoxin using ouabain as a separation means

A heterogeneous immunoassay for digoxin. An excess of labeled anti-digoxin antibody is added to a test sample and the resulting reaction mixture is contacted with a solid phase having ouabain immobilized thereon. All the free, labeled antibody binds to the oubain. The eluted digoxin anti-digoxin ant...

Beschreibung
Zusammenfassung:	A heterogeneous immunoassay for digoxin. An excess of labeled anti-digoxin antibody is added to a test sample and the resulting reaction mixture is contacted with a solid phase having ouabain immobilized thereon. All the free, labeled antibody binds to the oubain. The eluted digoxin anti-digoxin antibody complex is measured for label activity. A competitive mode is also disclosed.
