1 Characterization of the neutralizing activity of digoxin-specific Fab toward ouabain-like steroids. Digoxin FA complementation group B Homo sapiens
2 Digoxin-specific Fab (Digibind) is a mixture of antidigoxin Fab fragments prepared from sheep sera and is used as a treatment for digoxin poisoning. Digoxin FA complementation group B Homo sapiens
3 Digoxin-specific Fab (Digibind) is a mixture of antidigoxin Fab fragments prepared from sheep sera and is used as a treatment for digoxin poisoning. Digoxin FA complementation group B Homo sapiens
4 Digoxin-specific Fab (Digibind) is a mixture of antidigoxin Fab fragments prepared from sheep sera and is used as a treatment for digoxin poisoning. Digoxin FA complementation group B Homo sapiens
5 Digoxin-specific Fab has been shown to neutralize an endogenous Na+/K+ ATPase inhibitor (endogenous digoxin-like Na+/K+ ATPase regulatory factor; EDLF) in rats and humans and to lower blood pressure. Digoxin FA complementation group B Homo sapiens
6 In this study, some structural characteristics of EDLF were inferred from the ability of digoxin-specific Fab to neutralize the Na+/K+ ATPase inhibitory activity of several known cardenolides and bufodienolides. Digoxin FA complementation group B Homo sapiens
7 Digoxin-specific Fab had the ability to interact to some extent with all of the cardenolides and bufodienolides tested. Digoxin FA complementation group B Homo sapiens
8 However, digoxin-specific Fab was more than 20-fold more potent in neutralizing ouabain and bufalin than marinobufagenin. Digoxin FA complementation group B Homo sapiens
9 The antihypertensive effect of digoxin-specific Fab seen in preeclampsia and animal models of hypertension may therefore be due to a molecule identical to or structurally similar to ouabain or bufalin. Digoxin FA complementation group B Homo sapiens
