(1)一定の振幅又は直線的に増加する振幅の融合前電場波形を用いて処理された細胞よりも細胞融合効率が高い融合前電場波形を細胞に与える。
(2)細胞融合を行う細胞に振幅の大きい整列波形を即時にかけることによって生じる機械的な力、乱れ及び加熱を回避する。
(3)細胞融合に供する前に、細胞配列を整え、細胞膜接触を密にするために、融合前電場波形によって処理される細胞の加熱を低減する。
(4)細胞融合を行う前に、融合前電場波形によって処理された細胞間の細胞膜接触を密にする。
以上の所望の諸特性は、本発明における細胞融合用の独自のノンリニアー誘電泳動波形によって提供されるものであり、それらは以下の記述によって明らかになるであろう。従来技術に優る本発明の他の利点も、明確になるであろう。
