<p>As Fig. 1 shows, a test piece (10) for immunochromatography comprises a base (11) consisting of a sample introduction part (12), a labeling part (13) and an immobilization part (14). The base (11) is made of a material impregnated with a solvent of a sample solution containing a detection subject. Such a material allows the development of the solvent of the sample solution due to the capillary phenomenon. The sample introduction part (12) is an area into which the sample solution containing the detection subject is introduced (by, for example, dropping) and which carries a metal salt. The labeling part (13) contains a labeled antibody (15) labeled with a labeling in such state that it can be eluted into the sample solution. As the labeling antibody (15), use is made of one capable of binding specifically to the detection subject. In the immobilization part (14), an immobilized antibody (16) is immobilized. As the immobilized antibody (16), use is made of one capable of binding specifically to the detection subject.</p> |
