title: [Plasma membrane proteins of embryo cells of various sea urchin species and hybrid embryo].
abstract: Differences are observed in plasma membrane proteins of S. intermedius and S. droebachiensis sea urchin embryo cells isolated at middle blastula stage by means of acrylamide-gel electrophoresis in presence of SDS, urea or non-ionic detergents--Triton X-100 or Brij 35. Electrophoretic mobilities of plasma membrane proteins of sea urchin hybrid embryo malemale S. intermedius X femalefemale S. droebachiensis were identical with electrophoretic mobilities of plasma membrane proteins of maternal species S. droebachiensis. Three sea urchin embryo species under study had just the same biosynthesis of plasma membrane proteins at middle blastula stage detected by 14C-aminoacids pulse-labeling followed by membrane isolation, electrophoresis and gel-autoradiography.
