COLORECTAL CANCER MARKER GALECTIN, METHOD FOR ANALYZING GALECTIN CONCENTRATION IN BLOOD SAMPLE, AND KIT FOR DETECTING COLORECTAL CANCER MARKER GALECTIN

摘要

The present invention provides a tumor screening marker that can be actually used in clinical practice to detect colorectal cancer, and a tumor progression marker that can complement CEA or CA19-9. Galectin-1 used as a tumor screening marker or a tumor progression marker for colorectal cancer. Galectin-3 used as a tumor screening marker. Galectin-4 used as a tumor progression marker, a tumor screening marker, or a prognostic prediction marker for colorectal cancer. A method of analyzing the galectin concentration in a collected blood sample using the galectin. A colorectal cancer marker detection kit comprising a detection antibody selected from the group consisting of a fluorescently labeled galectin-1 antibody, a fluorescently labeled galectin-3 antibody, and a fluorescently labeled galectin-4 antibody.
