Method for amplification of signal in lateral flow assay by using water-soluble coating layer and lateral flow assay device using the method

摘要

The present invention relates to a method for analyzing an analyte comprising the step of binding an analyte with a conjugate in which a first antibody or a first specific binding substance capable of specifically binding to a first epitope or first binding site of an analyte is bound to a label, ; Binding an analyte to which the conjugate is bound and an immobilized second antibody or a second specific binding substance that specifically binds to a second epitope or second binding site of the analyte; And a signal amplification method in a lateral flow analysis, comprising the step of delaying the signal amplification material coated with a coating layer of a water-soluble substance and reacting the signal amplification material transferred thereto; And a lateral flow analyzer configured to perform the method of the present invention.
