  • Publication number: 20200386767
    Abstract: Provided are an analytical method and apparatus using fingerprints on the basis of the types and expression levels of expressed trace proteins and/or peptides contained in living tissue and/or biological fluid. The present invention relates to a method and apparatus for analyzing the status of living tissue and/or biological fluid by binding a specific fluorogenic reagent (such as DAABD-Cl) to expressed trace proteins and/or peptides contained in living tissue and/or biological fluid without degradation treatment followed by precisely detecting and separating by nano-liquid chromatography, and subsequently continuously and quantitatively measuring the separated and purified fluorescent labelled proteins and/or peptides using a fluorescence detector. The use of a nano-liquid chromatograph having a fluorescence detector makes it possible to obtain profiles of expressed trace proteins and/or peptides contained in living tissue and/or biological fluid.
