Abstract
The present study was performed to investigate the properties of ionic currents elicited by voltage pulses in the unfertilized eggs of mouse and hamster by using the whole cell voltage clamp techniques and to find out if there are any differences in properties between eggs of the two rodents. In addition, the modulatory effect of G proteins and protein kinase C (PKC) on the ionic channels were observed. The inward current in hamster eggs was shown to be due to
