Abstract
Isolated cortices from sea urchin eggs accumulate calcium in a non-mitochondrial store at a rate dependent on ATP and enhanced by oxalate. Calcium efflux is increased by ionomycin and by A23187 which has been used as a parthenogenetic agent, but not by weak base (NH4Cl). Accumulated calcium is partially released by 1,4,5 inositol triphosphate.Keywords
