Abstract

A method for simultaneously detecting a plurality of target polynucleotides in a sample on a single reaction chip and a method for separating a plurality of target polynucleotides are provided. On the reaction chip are arranged a plurality of independent cells for capturing different target polynucleotides. Different probes are immobilized onto the individual cells, and labeled probes detect the cells where the target polynucleotides are captured, thereby analyzing the species of the captured target polynucleotides. Also, the individual cells function as electrodes to elute the captured target polynucleotides therethrough, thereby separating a plurality of the target polynucleotides.
