Acid release at meiotic maturation of oocytes in the polychaete annelid Sabellaria alveolata.
ABout 1 pmole of acid per egg is released when prophasic oocytes undergo maturation under the action of sperm, proteases or ionophore A 23187. No similar acid release occurs at fertilization of matured oocytes. These findings are compared with data on Urechis and sea urchin.
