  • Patent number: 8143004
    Abstract: A method for measuring a test substance whereby the test substance in a sample can be specifically measured without using an antibody against the test substance; an aptamer molecule used therefor; and a method for creating the aptamer are disclosed. An aptamer capable of hybridizing with an oligonucleotide when it is bound to a test substance, but is incapable of hybridizing with the oligonucleotide when it is not bound to the test substance, is utilized. The aptamer is brought into contact with a sample, and the aptamer bound to the test substance is brought into contact with an immobilized oligonucleotide which hybridizes with the aptamer, to bind the aptamer to a solid phase, followed by measurement of the aptamer immobilized on the solid phase.
