  • Publication number: 20220099670
    Abstract: Disclosed is a method for detecting regulatory dendritic cells, the method comprising step a: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step b: identifying regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Also disclosed is a method for producing a cell population enriched for regulatory dendritic cells, the method comprising step 1: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step 2: obtaining a cell population enriched for regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Further disclosed is a cell population enriched for regulatory dendritic cells obtained by the method.

  • Publication number: 20210039364
    Abstract: [Object] A laminate is provided which can form packaging bags having a wide range of packaging feasible temperatures and excellent high-speed liquid packaging properties. [Solution] The laminate includes a sealant layer and an intermediate layer disposed in contact with the sealant layer, the sealant layer including an ethylene/?-olefin copolymer satisfying the requirements (x0) to (x3). (x0) The copolymer is a copolymer of ethylene and a C3-C20 ?-olefin. (x1) The MFR is 1 to 50 g/10 min. (x2) The density is 890 to 910 kg/m3. (x3) 0.35??H (80)/?H?0.85, and 0.60??H (100)/?H?0.85, wherein ?H is the total heat of melting observed during DSC, and ?H (T) is the heat of melting observed during heating from 0° C. to T° C.

  • Publication number: 20210009794
    Abstract: An object of the present invention is to provide a resin composition for a sealant combining bag manufacturing performance and inflation film process-ability (extrusion properties, bubble stability), a sealant film and a heat-fusible film produced using the composition, and a package produced using the heat-fusible film. The ethylene-based resin composition for a sealant according to the present invention satisfies the following requirements (1) to (3) simultaneously: (1) a melt index (I21: 190° C., 21.6 kg load) is 42 to 80 g/10 min; (2) a ratio I21/I2 of the melt index (I21: 190° C., 21.6 kg load) to a melt index (I2: 190° C., 2.16 kg load) is 5 to 25; (3) a melt tension (190° C.) is 25 to 180 mN.
