METHOD OF DETECTING TEST SUBSTANCE, SAMPLE ANALYSIS CARTRIDGE, AND SAMPLE ANALYZER

摘要

In a method of detecting a test substance, a test substance is detected using a sample analysis cartridge supplied with a sample. The sample analysis cartridge includes: a passage part having a gas-phase space; and liquid containers communicating with the passage part through openings. The liquid containers include: a first liquid container containing a first liquid containing magnetic particles; and a second liquid container containing a second liquid containing a labeled substance 42. The magnetic particles are sequentially transported to the liquid containers through the gas-phase space in the passage part. Thus, the magnetic particles carry a complex of the test substance and the labeled substance. The test substance is detected based on the labeled substance in the complex.

主权项

1. A method of detecting a test substance contained in a sample by a sample analysis cartridge supplied with the sample,
the sample analysis cartridge including a passage part with a gas-phase space; and liquid containers disposed along the passage part and communicating with the passage part through openings, wherein the liquid containers include a first liquid container containing a first liquid containing magnetic particles that carries the test substance, and a second liquid container containing a second liquid containing a labeled substance that can be coupled to the test substance, the method comprising: sequentially transporting the magnetic particles to the liquid containers through the gas-phase space in the passage part; allowing the magnetic particles to carry a complex of the test substance and the labeled substance; and detecting the test substance based on the labeled substance in the complex.
