Abstract E. Habermann, M. Hudel and M.-E. Dauzenroth. Palytoxin promotes potassium
outflow from erythrocytes, HeLa and bovine adrenomedullary cells through its interaction …

Palytoxin (about 1 pM) increases the permeability of human erythrocytes. We now report its
radiolabeling with 125 I, followed by affinity purification on porcine kidney membranes. The …

Summary Hog kidney Na+, K+-ATPase, purified to the microsomal stage and activated with
detergent, binds palytoxin, as shown by the nearly complete competition of the toxin with 3 H …

E. Habermann. Palytoxin acts through Na+, K+-ATPase. Toxicon27, 1171–1187, 1989.—
Palytoxin is the most potent animal toxin, with a unique structure. The author's group has …

Palytoxin increases the permeability of human erythrocytes and their resealed ghosts. To
elucidate its mode of action the activation by ATP and Ca 2+, the inhibition by ouabain, and …

Palytoxin in concentrations as low as 1 pM raises the potassium permeability of rat, human
and sheep erythrocytes, and the sodium permeability of human erythrocytes. The release of …

Palytoxin (PTX), at extremely low concentrations (0.01–1nM), caused K+ release from rabbit
erythrocytes. Among the various chemical compounds tested, cardiac glycosides potently …

Palytoxin is a haemolysin. The erythrocytes from various species can be classified into a
sensitive and a hardly sensitive group. The former contain potassium as their main inside …

Palytoxin causes within minutes a temperature-dependent K+ loss from human and rat
erythrocytes which is followed within hours by haemolysis. It decreases the osmotic …

Palytoxin (PTX) caused K+ release from rabbit erythrocytes which was dependent on the
concentrations of extracellular Ca 2+ and PTX. In a Ca 2+-free solution, PTX still caused a …
