## Abstract Contents of the tricarboxylic acid (TCA) cycle intermediates, coenzyme A (CoA) derivatives, and carnitine derivatives were estimated in the developing eggs and embryos of the sea urchin, __Anthocidaris crassispina__. Levels of the TCA cycle intermediates in unfertilized eggs were simila
## Abstract Phosphatase activity in sea urchin embryonic antigens was investigated by histochemical staining of immunoprecipitates separated by twoβdimensional (crossed) immunoelectrophoresis. Unfertilized eggs were homogenized in a hypotonic medium which solubilized cytoplasmic antigens. Antigens
## Abstract Phosphatase activities in sea urchin eggs and plutei were investigated by means of histochemical staining of immunoprecipitates. Two protein fractions were obtained by extraction in a hypotonic medium and by detergent treatment of the residual pellet. Three distinctly different phosphat
