Abstract: In order to provide a specific solution for producing a microstructure equipped with a mechanism for selectively detecting a marker molecule expressed by a target cell, or a specific biomolecule, and for detecting and identifying a molecule to be detected using the microstructure, the present invention provides a nearly hemispherical shell-shaped structure made of a first conductive material, and an electrode layer made of a second conductive material disposed on the concave side of the nearly hemispherical shell-shaped structure, wherein the first conductive material includes a magnetic material and the second conductive material includes an electrode material, and the size (diameter) of the cavity surrounded by the electrode layer on the concave side of the nearly hemispherical shell-shaped structure is in the range of about 10 nm to about 50 ?m.

Abstract: A cell-spreading device may include a microchamber chip having a microchamber capable of enclosing and retaining a cell, a channel-forming frame united with the microchamber chip to form a channel on the microchamber, an inlet provided in the channel-forming frame to allow a cell suspension to flow into the channel, and an outlet provided in the channel-forming frame to allow the cell suspension, which has been allowed to flow into the channel through the inlet, to flow out from the channel. When an aperture of the microchamber is projected perpendicularly to a longitudinal width of the microchamber chip, the void ratio that is a ratio of the sum total of voids to the longitudinal width is not more than 5%, the void being a length of a portion where the projected aperture of the microchamber is not present against the longitudinal width.

Abstract: Disclosed is a detection method for detecting a specific cell in a sample containing multiple cells including the specific cell. Specifically disclosed is a detection method for detecting a specific cell in a sample containing multiple cells including the specific cell, which comprises the following steps (1) and (2): (1) retaining cells contained in the sample on a microarray chip which comprises multiple microchambers, wherein each of the microchambers can contain multiple cells; and (2) confirming the presence or absence of the specific cell in the cells retained on the microarray chip.

Abstract: Provided is a micro chamber chip for cell expansion, with which the non-specific adsorption of cells onto a surface other than a micro chamber can be suppressed, and a rare cell from a substance that contains a large quantity of cells, such as a blood, can be stored, held and observed without a leakage of the rare cell. A micro chamber chip for cell expansion is provided with a micro chamber chip in which a micro chamber configured to store and hold one or more cells is formed on an upper surface of a substrate, wherein an upper surface of the micro chamber chip and an inner wall surface of the micro chamber are coated with a blocking agent that can suppress a non-specific adsorption of a cell on the upper surface.

Abstract: The present invention provides: genetically modified yeasts such as mutant yeasts having an ability to produce N-linked sugar chains of Man5GlcNAc2 and a decreased ability to produce O-linked sugar chains, mutant yeasts having an ability to produce N-linked sugar chains of Man5GlcNAc2 and further having an ability to produce N-linked sugar chains of GlcNAc1Man5GlcNAc2, and mutant yeasts having an increased ability to produce and secrete proteins and an ability to produce N-linked sugar chains of Man5GlcNAc2; and a method for producing glycoproteins using them.

Abstract: A chip useful for treating cells and the like which has a mechanism and a structure wherein the size of a hole pattern is arbitrarily changed so that cells can easily move in and get out from the hole in scattering or collecting cells but can hardly get out from the hole during washing or antigen-stimulation. The chip comprises a crosslinked product of a temperature-responsive polymer as a constituting member and being provided with a film having a hole pattern on the surface of a baseboard. A method of producing the chip comprises applying a composition containing a crosslinkable temperature-responsive polymer on the surface of a baseboard to thereby form a coating film, crosslinking the coating film to thereby form the crosslinked product as described above and then forming a hole pattern on the coating film of the crosslinked product.
