Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campisi, J -- Scandella, C J -- New York, N.Y. -- Science. 1978 Mar 24;199(4335):1336-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/564549" target="_blank"〉PubMed〈/a〉
