NUCLEIC-ACID-REACTIVE GEL, METHOD FOR PRODUCTION OF THE GEL, AND USE OF THE GEL

摘要

Disclosed is a nucleic-acid-reactive gel whose volume change can be improved by properly designing the structure thereof, whose ability of recognizing a nucleic acid is controllable, which has an improved sensitivity, and which can be designed readily according to the sequence of target DNA or the like. The nucleic-acid-reactive gel comprises a polymer gel and a probe composed of two single-stranded nucleic acid molecule hybridizing with each other and immobilized in the network structure of the polymer gel, wherein the two single-stranded nucleic acid molecules in the probe are bound to each other in a reversible manner.
