DETECTION METHOD AND QUANTIFICATION METHOD OF DETECTION TARGET

摘要

Provided are a detection method and a quantification method for a detection target, which can detect and quantify the detection target rapidly, inexpensively, simply, and with high accuracy in a variety of environments. A method for detecting the detection target in a specimen includes processes in which there are mixed a first binding substance which binds a first material containing a stimuli-responsive polymer and a first affinity substance which has affinity for the detection target, a second binding substance which binds a hydrophilic second material and a second affinity substance which has affinity for the detection target, and a specimen; the resulting mixture is placed under conditions where the stimuli-responsive polymer agglutinates and the mixture is developed into a developing carrier, or the resulting mixture is developed into a developing carrier and the mixture is placed under conditions where the stimuli-responsive polymer agglutinates; the signal produced by the presence of the first binding substance or the second binding substance in the developing carrier is verified; and the presence of the detection target in the specimen is determined when the signal is different from that when the detection target is absent. The first affinity substance and the second affinity substance can bind to different positions of the detection target.
