Acid phosphatase (activity expressed as optical density), apyrase (optical den- sity), succinic dehydrogenase (A log ferricytochrome c/3 minutes) and ribonucleic acid (optical density) in homogenates of Ciona eggs. The data for eighteen paired measurements of acid phosphatase in anterior and posterior cells are summarized in Table I. The anterior cells contain 12 per cent more

Acid phosphatase (activity expressed as optical density), apyrase (optical den- sity), succinic dehydrogenase (A log ferricytochrome c/3 minutes) and ribonucleic acid (optical density) in homogenates of Ciona eggs. The data for eighteen paired measurements of acid phosphatase in anterior and posterior cells are summarized in Table I. The anterior cells contain 12 per cent more of this enzyme than posterior cells, a difference which is significant at the one per cent level. A number of these experiments were carried out using sodium de- soxycholate in the homogenization medium, with no detectable increase in enzyme activity.
