The present invention provides a method for detecting an antigen in an analysis sample, the method including: (a) contacting an analysis sample with a detection antibody with which a marker generating a detectable signal is combined and which specifically binds to the antigen; (b) contacting a capture antibody with the resultant product of step (a), the capture antibody specifically binding to an antigen to be detected; (c) contacting the detection antibody, with which the marker generating a detectable signal is combined, with a reference substance which is bound to a surface of a solid substrate and which includes an epitope to which the detection antibody specifically binds; (d) measuring signals generated from the markers of the resultant product of step (b) and the resultant product of step (c); and (e) analyzing the measured signals to determine the presence or absence and amount of the antigen in the analysis sample. The method for detecting an antigen of the present invention can control the flow and the reaction time of an analysis sample, thereby improving sensitivity and minimizing the influences by the concentration of the analysis sample or the temperature of the detection reaction, and thus improving stability, reliability, and reproducibility of data, when compared with the conventional method for detecting an antigen. Accordingly, the method and apparatus for detecting an antigen of the present invention can be easily operated without specialized skills, thereby instantly obtaining the presence or absence and amount of detection antigen in the analysis sample through on-site diagnosis.

Method for detecting antigen, and apparatus using same

A fluorescent microscope for observing multiple fluorescent images includes: a first optical module comprising a first light source for supplying first excitation light having a first wavelength, a first excitation filter for selectively transmitting the first excitation light supplied from the first light source, a first dichroic filter for reflecting the first excitation light having passed through the first excitation filter toward the survey object, an objective lens for condensing the first excitation light reflected by the first dichroic filter and transferring the condensed first excitation light to the survey object, a second dichroic filter for reflecting first radiation light radiated from the survey object, a first radiation filter for selectively transmitting the first radiation light reflected by the second dichroic filter, and a first image acquisition unit for acquiring an image by using the first radiation light having passed through the first radiation filter to be supplied; and a second optical module comprising a second light source for supplying second excitation light having a second wavelength, a second excitation filter for selectively transmitting the second excitation light supplied from the second light source, a second radiation filter passing through the second excitation filter and irradiated to the survey object to be radiated, to selectively transmitting the second radiation light EMhaving passed through the objective lens, the first dichroic filter, and the second excitation filter, and a second image acquisition unit for acquiring an image by using the second radiation light having passed through the second radiation filter to be supplied.
