Fertilization-induced changes in membrane fluidity of sea urchin eggs
Science (New York, N.Y.)
|March 24, 1978
Abstract:
By use of a spin label fatty acid, 5-doxylstearate, an increase in bulk membrane fluidity was observed after fertilization of two species of sea urchin eggs. Eggs partially activated by ammonia showed a similar effect. The data suggest that a structural change involving membrane lipids accompanies activation.
