摘要:
A human antibody that has a specific reactivity with multiple tumor cell lines including ATL cells and possesses both safety and therapeutic efficacy and a fragment of said antibody are provided. A human antibody and a fragment of said antibody that may recognize HLA-DR β chain expressed on the surface of tumor cells were obtained. In particular, it was found that a dimer of scFv (diabody) of said antibody may induce potent apoptosis in cells expressing the HLA-DR β chain. The antibody and a fragment of said antibody obtained in accordance with the present invention are useful for a detection reagent, a diagnostic and a medicament for protection or treatment of cancers including ATL and/or viral infectious diseases.

This invention has as its object to provide an image sensing apparatus which can satisfactorily correct misregistration among images, and can composite the images. To achieve this object, an image sensing apparatus includes: a plurality of apertures that receives external light from different positions; a plurality of image sensing units that outputs image signals obtained by independently receiving light that comes from an identical position of an object and is received via the plurality of apertures, and independently extracting predetermined color components for each received light; and a signal processing device that forms a signal that outputs an object image by mixing the image signals output from the plurality of image sensing units. When it is determined that a predetermined position deviation occurs between the image signals upon forming the signal that outputs the object image, the signal processing device corrects the predetermined position deviation by a signal process, and forms the signal that outputs the object image.

An optical apparatus is disclosed, which can take high-quality images by using light transmitted through a beam splitter. The optical apparatus comprises a light-receiving element and a beam splitter. The first surface of the beam splitter reflects part of incident light and transmits the other part of the incident light toward the light-receiving element. The second surface transmits other incident light other than the incident light to the first surface toward the light-receiving element. The transmittance of the second surface is set so that a light amount distribution on the light-receiving element may be substantially even in a case where the light is incident to the first and second surfaces from an object having a substantially even luminance.
