Problems solved by technology

[0014] However, it is difficult for existing analytical methods to effectively extract or release markers such as magnetic particles in the pores
[0015] Furthermore, the problem with existing analytical methods is that only one magnetic particle can be examined at a time, which takes a long time and complicates the examination

Abstract

The present invention relates to an automated immunoassay device and method. The automated immunoassay device comprises: a cartridge (13) in which a T tip tube (9), a reactive tube (11), a washing tube (3), and a signal measuring tube (5) are integrally connected to one another or separately arranged; a T tip (7) and a magnetic rod (31) which enter the multiple tubes (3, 5) sequentially to allow the migration of large magnetic particles (m), a capturing material, a signal material, and an analysis material by magnetic force, with the concomitant performance of reactions and washing processes;a cartridge holder (15) on which the cartridge (13) is stably placed; and a heating member (17) disposed in an area in which the reactive tube (11) is stably placed on the cartridge holder (15) so asto generate heat, wherein the large magnetic particles (m) comprise morphologically identical or different magnetic particles to which a material capable of capturing only a specific analysis materialper each of the morphologically different magnetic particles is coupled.

Description

technical field [0001] The present invention relates to an automatic immunoassay device and method, and more particularly, relates to a technology for providing an immunoassay device and method thereof by improving the structure, which automatically performs the following process by using a magnetic bar and a T-shaped tip A simple method for the extraction and release of large magnetic particles of various shapes, by using large magnetic particles in one cartridge for washing to improve the accuracy of immunoreaction results, and by image analysis in one tube for various shapes of Large magnetic particles perform multiple inspections at once. Background technique [0002] At present, with the completion of the Human Genome Project and the advent of the post-genome era, a large amount of microscopic information has been generated, which is difficult to quickly analyze in related experimental analysis systems. [0003] In accordance with this trend, bioassay systems for ident...
