The role of vitamin E in preventing the hemolysis of kid and chick erythrocytes with Tween 20.

Erythrocytes of vitamin E-deficient kids and chicks were hemolyzed at concentrations of Tween 20 above 1%. In vivo or in vitro uptake of vitamin E by the erythrocytes, or the addition of dithiothreitol or 2-mercaptoethanol, prevented the hemolysis with Tween 20.
