  • Patent number: 8093361
    Abstract: The present invention provides an antibody which specifically recognizes three-dimensional structure of an extracellular region of a polypeptide encoded by PERP (p53 apoptosis effector related to PMP-22) gene and binds to the extracellular region. The antibody of the present invention is useful for treatment of various diseases which highly expresses a polypeptide encoded by the PERP gene. Also, a polypeptide encoded by the PERP gene or a cell expressing the polypeptide can be specifically detected by an immunological method using the antibody, so that the antibody is useful for diagnosis of various diseases related to PERP.

  • Patent number: 7675051
    Abstract: An image forming apparatus includes an image forming mechanism, a sheet conveyance mechanism, and a sheet detector. The image forming mechanism forms an image and transfers it onto the sheet conveyed by the sheet conveyance mechanism. The sheet detector is arranged upstream from an image transfer region and configured to detect the sheet. The sheet detector includes a light source, a plurality of photoreceptors, and a controller. The plurality of photoreceptors is arranged in line in a main-scanning direction and includes a first photoreceptor group and a second photoreceptor group. The first photoreceptor group changes output voltages when overridden by the side edge of the sheet. The second photoreceptor group includes an opposite end of the plurality of photoreceptors being out of the side edge of the sheet. The controller is configured to adjust a light emission amount in accordance with characteristics of the sheet.
