EFFECTS OF ROENTGEN RADIATION ON THE JELLY OF THE ARBACIA EGG

Abstract
Roentgen radiation (6,100 r) removed the jelly from the Arbacia egg. When the jelly was mechanically removed from the eggs it was detected in the supernatant fluid by its reaction with Janus green. An irradiation of 61,000 r altered the jelly so that the Janus green test became negative. The jelly was not affected by solns. previously irradiated. The radiation produced a slight shift in the pH of unbuffered egg-water toward the acid side. The action of the radiation was apparently directly on the jelly particles.
