  • Publication number: 20130314526
    Abstract: Provided is a cell concentration/purification device having a function of successively locating cells in a specific area of a microchannel, and a function of sequentially capturing cell images by use of light from a plurality of monochromatic light sources on an image basis, and performing comparative analysis of the cell images to recognize individual cells based on information on the shape of the cells and an absorption spectral distribution of the cells or inside of the cells, thereby selectively separating/purifying the cells.

  • Patent number: 8372647
    Abstract: The present invention provides novel markers for diagnosing pancreatic cancer, and methods for determining if a subject has pancreatic cancer utilizing the markers, etc. The methods involve comparing mass-spectrometric peaks of certain sugar chains, obtained from patients' blood and determining if there is a significant decrease in peak intensity, compared with corresponding peaks from patients without pancreatic cancer.

  • Publication number: 20110065141
    Abstract: The present invention is to provide a novel marker for diagnosing pancreatic cancer, a method for determining if a subject has pancreatic cancer utilizing the marker, etc. The present inventors collected blood from patients of 78 cases in total including patients of 24 cases with pancreaticobiliary-duct benign disorder (16 gallstone cases and 8 pancreatitis cases) and patients of 54 cases with pancreatic cancer, and mass spectrometry was performed on N-linked sugar chains in plasma. From the 74 mass-spectrometric peaks detected, 65 sugar chains were extracted based on the results of PAM analysis. These extracted sugar chains were then used to predict pancreatic cancer or pancreaticobiliary-duct benign disorder, to correctly diagnose 74% cases.
