## Abstract Decreased glycogen radioactivity was followed as an indicator of glycogen utilization following activation of __Strongylocentrotus purpuratus__ eggs. Within 15 minutes of exposure to sperm or ammonia, egg glycogen radioactivity decreased. The level of radioactivity in control (unfertili
Rabbit antisera to homogenates of unfertilized sea urchin eggs were absorbed with pluteus extract. In the same way, antisera to gastrulae or plutei were also made. "stage specific" by absorption with extracts of eggs. When tested by means of immunoelectrophoresis the absorbed sera formed precipitate
