The present disclosure provides a membrane separation method of a cell suspension which can appropriately separate cells from debris, and a cell culture device. That is, membrane separation processing of the cell suspension is performed using a filtration membrane which includes an inlet-side opening formed on one surface and an outlet-side opening, which is formed on the other surface and communicates with the inlet-side opening, and in which the inlet-side opening and the outlet-side opening are disposed at positions deviated in a direction parallel to the surfaces of the membrane.

Membrane separation method of cell suspension, and cell culture device

A culture container has a first inflow port and a first outflow port. The first flow path connects the first outflow port to the first inflow port. A storage container is provided within the first flow path and has a second inflow port which is connected to the first outflow port and a second outflow port which is connected to the first inflow port. A second flow path connects a first region within the first flow path, and a second region within the first flow path. A division processing portion is provided within the second flow path, performs a division process of dividing a cell aggregation flowing in from the first flow path, and allows the cells subjected to the division process to flow out into the first flow path via the second region. A medium supply portion supplies a medium to the inside of the first flow path.

Cell culture device and cell culture method

There is provided a cell culture bag including: plural tubular portions having gas permeability in which a tube axis direction is directed to a first direction and which are arranged side by side in a second direction intersecting with the first direction and are separated from each other using a partition wall; and communication portions having gas permeability which allow communication between two mutually adjacent tubular portions of the plural tubular portions in an intermediate region R between one end and the other end of the tubular portions.

Cell culture bag and cell culture method

The present invention provides a polarizing plate that includes a polarizer, and an optical film including an alignment layer, an optically anisotropic layer, and an optically isotropic acrylic polymer layer on at least one surface of the polarizer, in which the optically anisotropic layer is a layer formed by irradiating a polymerizable composition including a liquid crystal compound that is directly applied to the alignment layer with light to polymerize the liquid crystal compound, the acrylic polymer layer is a layer formed by curing a polymerizable composition including (meth)acrylate that is directly applied to a surface of the layer formed from the polymerizable composition including a liquid crystal compound, and the thickness of the acrylic polymer layer is larger than the thickness of the optically anisotropic layer. According to the present invention, it is possible to provide a polarizing plate having a small thickness.

Polarizing plate comprising an optical film including an alignment layer, an anisotropic layer, and an isotropic acrylic polymer layer and method for producing the same

The method includes: forming a coating film including particles and an ultraviolet curable resin on a film substrate; and curing the ultraviolet curable resin by ultraviolet irradiation to form an anti-glare layer constituted by the particles and the ultraviolet curable resin. A ratio of a thickness A of the anti-glare layer to a diameter B of the particles is in the range of 1.5 to 2.4. The ultraviolet irradiation is performed with two or more ultraviolet irradiation units, the first unit irradiation amount is 49 mJ/cmor less, the second and subsequent units irradiation amount is greater than 50 mJ/cm, and the total irradiation amount is 100 mJ/cmor greater. The oxygen concentration at a position which is 1 mm above a surface of the coating film is 1 ppm to 2000 ppm. The first unit irradiation is performed above a roller with surface temperature of 10&#xb0; C. to 24&#xb0; C.
