Title:
IMMUNOCHROMATOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2021/152965
Kind Code:
A1
Abstract:
Provided is immunochromatography having high detection sensitivity. Immunochromatography comprising: a concentration step for concentrating a liquid that could contain an antigen by means of ultrafiltration to obtain a concentrated antigen liquid; a development step for, after causing the formation of a particle complex that is a complex of the antigen in the concentrated antigen liquid and of a modified particle which is a particle modified by a first binding substance capable of binding with the antigen, developing the particle complex on an insoluble carrier having a reaction site on which a second binding substance capable of binding with the antigen is immobilized; a capture step for capturing the particle complex on the reaction site of the insoluble carrier; and an amplification step for amplifying information pertaining to the particle complex captured in the capture step.
