Abstract
A cancer cell detection method that makes it possible to perform imaging of cells in a living state and a dual detection method for cancer cells in which the aforementioned method is combined with a pre-existing dyeing method for cytodiagnosis. The method uses living body-derived cells and includes: incubating living cells included in a sample taken from a person together with a fluorescently-labeled L-glucose derivative and detecting the fluorescently-labeled L-glucose derivative that is taken up into the cells; and detecting fluorescence emitted by the L-glucose derivative that is present within the cells while the cells are attached to a thin glass or plastic plate. Also provided is a dual detection method for cancer cells in which the cancer cell detection method that uses living body-derived cells is combined with a dyeing method using cells that are fixed using an alcohol or the like.
