摘要： Regions where metastatic cancer cells can exist are detected with high accuracy in a sentinel lymph node. Quantum dots are injected into the vicinity of a cancer in a living body, thereby identifying the location of the sentinel lymph node by means of fluorescence. Subsequently, the sentinel lymph node is extracted. With respect to the sentinel lymph node extracted with quantum dots injected, structural analysis is conducted by means of precision fluorescence measurement which uses a confocal fluorescence microscope for monomolecular observation. Specifically, the fluorescence intensity is measured with respect to each of multiple areas in the sentinel lymph nodes, and out of the multiple areas measured, one or more areas are detected as afferent lymph vessel inflow regions in descending order of fluorescence intensity.

摘要： The present invention provides a biological substance detection method for specifically detecting a biological substance from a pathological specimen, by which method, when immunostaining using a fluorescent label and staining for morphological observation using a staining agent for morphological observation are simultaneously performed, the results of fluorescence observation and immunostaining can be assessed properly even if the fluorescent label and/or the staining agent is/are deteriorated by irradiation with an excitation light. The biological substance detection method according to the present invention is characterized in that the brightness retention rate of an immunostained part is in a range of 80% to 120% in relation to the brightness retention rate of apart stained for morphological observation when the fluorescent label used for the immunostaining is observed.
