    摘要: The present invention is directed to a method for producing an optical fiber having formyl groups on a core surface. In one embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by immersing the core surface of the plastic optical fiber in a treating solution containing at least a 0.5 to 40 mM alkali metal hydroxide and a compound having formyl groups in water or lower alcohol solvent. In the other embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by introducing a vic-diol group, a primary hydroxyl group or an alkenyl group on the core surface, and then oxidizing it. Turbidity on the core surface of the optical fiber thus obtained is minimized, thereby reducing the transmittance losses of light.

    摘要: The present invention relates to an apparatus for performing a fluoroimmunoassay, the apparatus comprising an excitation light source, a fluorescence detector, an optical fiber for an excitation light from the excitation light source to which an antigen or antibody is bound, and a spectroscope, in which the mentioned antigen or antibody is bound to an outgoing end surface of the optical fiber for the excitation light. In the apparatus the spectroscope is constructed so that it introduces the excitation light emitted from the excitation light source to a incident end surface of the optical fiber for the excitation light and introduces a fluorescence emitted from a fluorescence-labeled antibody or antigen which forms an immunological complex with the antigen or antibody to the fluorescence detector. In the apparatus the outgoing end surface of the optical fiber for the excitation light has a transmittance for the excitation light from the excitation light source. The invention also relates to a sensing chip which is used in the apparatus for performing a fluoroimmunoassay therewith.

    摘要: Epidermal keratinocytes not incorporating magnetic particles therein and epidermal keratinocytes incorporating magnetic particles therein were seeded in a 24-well ultra-low-attachment plate, and cultured for one day after a neodymium magnet was placed outside the bottom of the well. As a result, control epidermal keratinocytes not incorporating magnetic particles therein did not adhere to the bottom of the well and did not form an undifferentiated cell sheet. On the contrary, epidermal keratinocytes incorporating magnetic particles therein, while being attracted to the bottom of the well by magnetic force, formed a multilayered cell sheet. This cell sheet could be easily recovered by removing the neodymium magnet placed outside the bottom of the well, then bringing a magnet having a hydrophilic film attached thereto close to the cell sheet from upside and to attract it via this hydrophilic film, and lifting it.

    摘要: A cell culture method prepares first cells that are adhesion-dependent cells and monolayered or multilayered cells on a culture surface of a culture substrate, seeds second cells that are adhesion-dependent cells and are magnetized by allowing to have magnetic particles on the first cells, induces the second cells to a predetermined position on the first cells by magnetic force, and cultures the first cells and the second cells in a cell arrangement obtained by the magnetic induction. According to this cell culture method, after a cell sheet was prepared individually, cells can be multilayered without changing a temperature, peeling the monolayered sheet and laminating the monolayered sheets.
