Diamide reversibly induces a stress response in the sea urchin, Arbacia punctulata.


Sea urchin blastulae were treated with two concentrations (0.54 and 0.72 mM) of diamide, a sulfhydryl oxidant, after hatching. These treatments increased the relative synthesis of one set of embryonic proteins while decreasing that of another. This was demonstrated by quantitating the incorporation of [35S]methionine into polypeptides separated by 2… (More)
