Method for detection of antigen using fluorescence resonance energy transfer immunoassay on membrane

摘要

The method for detecting an antigen according to an embodiment of the present invention comprises the steps of (a) contacting a sample containing an antigen to be detected with the other end of a diagnostic unit formed of a membrane containing an antibody against the antigen to be detected, Process; (b) irradiating the antigen-antibody complex formed by the step (a) with light to cause fluorescence resonance energy transfer and obtaining a spectrum therefrom; And (c) analyzing the spectrum obtained in the step (b) to determine the presence or absence of the antigen to be detected and measuring the concentration.
