ELECTRIC IMPEDANCE OF ASTERIAS EGGS [PDF]

Journal of General Physiology, 1936
The alternating current resistance and capacity of suspensions of unfertilized eggs of Asterias forbesi have been measured at frequencies from one thousand to sixteen million cycles per second. The plasma membrane of the egg has a static capacity of 1.10µf/cm.2 which is practically independent of frequency.
