Apparatus for microinjection of sample into amphibian oocytes

An automatic electrophysiological measuring apparatus to automatically penetrate a glass electrode(s) into the membrane of a Xenopus Oocyte to hold the membrane potential and to automatically measure reactions to the administration of a medicine is to be provided. A glass electrode in the air is moved toward a Xenopus Oocyte held in a cell. Changes in the potential states of the glass electrodes are picked up by a control computer to distinguish the relative positions of the glass electrode and the Xenopus Oocyte , and the sequence of electrophysiological measurement so as to penetrate the glass electrode into the Xenopus Oocyte , hold the membrane potential and automatically administer the medicine.
