Hybridization method and sensor chip hybridization and detection unit

摘要

PPROBLEM TO BE SOLVED: To improve the hybridization efficiency by adopting a device so as to arrange and fix a nucleotide chain for sensing an elongated state. PSOLUTION: A hybridization sensing part 1a, etc., are composed so as to fix a reaction region R to be a site for hybridization between a nucleotide chain X for sensing and a target nucleotide chain Y having a base sequence complementary to the nucleotide chain X for sensing to an end of a scanning electrode C by dielectrophoretic actions while elongating the nucleotide chain X for sensing with an electric field. Thereby, a sensor chip equipped with the sensing part 1a, etc. and a method for hybridization using the hybridization sensing part and sensor chip are provided. PCOPYRIGHT: (C)2004,JPO
