METHOD FOR DIAGNOSING A BIOMARKER AND BIOMARKER DIAGNOSIS KIT

摘要

The present invention provides a method for diagnosing a biomarker and a biomarker diagnosis kit using a magnetic particle and a quantum dot for quantitative analysis. The method for diagnosing a biomarker comprises; (i) a step of providing magnetic particles in which a first antibody capable of collecting a biomarker is fixated on the surface using a linker; (ii) a step of providing quantum dots in which a second antibody capable of detecting the biomarker is fixated on the surface; (iii) a step of targeting and sandwiching the biomarker by the magnetic particles and the quantum dots; (iv) a step of selectively separating the quantum dots which targets and sandwiches the biomarker between the quantum dots; and (v) a step of quantifying the concentration of the biomarker by measuring the optical density or fluorescent density of the separated quantum dots.
