Abstract
Using the whole cell voltage clamp technique to clamp sea urchin oocytes we show that the fertilising spermatozoon triggers an inward current at activation. Symultaneously the plasma membrane depolarises and the conductance increases. Since injection of inositol triphospate induced an inward current and this current was inhibited by preloading oocytes with the calcium chelator BAPTA.File in questo prodotto:
