Electrode for electrical cell fusion and electrical introduction of nucleic acids.

摘要

This aim of this invention is to make possible efficient, large-scale cell fusion and introduction of nucleic acids by the electrical method. An electrode of which a contact part has an overall cross-section matching the shape of the base of a cylindrical container for cell culture, and wherein electrical cell fusion and electrical introduction of nucleic acids are performed by applying an A.C. voltage to a plurality of conductors so as to generate an electrical field, and applying a D.C. pulse in synchronism, is characterized in that these conductors are disposed such that the cross-section of the contact part consists of a series of concentric rings formed by the conductors, in that the conductors have flat surfaces, and in that the conductors or their surfaces consist of a stable material which does not easily ionize. <IMAGE>
