An apparatus and method for separating a target material. The apparatus for separating a target matter includes a mixture including a target matter, a density gradient material layer disposed under the mixture and having a greater density than a density of the mixture, magnetic beads including a magnetic material and binding to the target matter to form a complex, and a magnetic field generating device applying a magnetic field to the complex to precipitate the complex at the bottom of the density gradient material layer.

Kits and systems for isolating microorganisms from a sample, the sample including sample matrix and microorganisms, the kit including concentration agent; and a system for isolating microorganisms from a sample.

A system and method for the label-free analysis of cells includes a purification device configured to receive a heterogeneous population of cells, the purification device temporarily trapping therein a subpopulation of cells from the heterogeneous population of cells and a cell analysis device positioned downstream of the purification device and configured to measure one or more cellular parameters including cell count, measured cell size, and/or cell morphology. In an alternative embodiment, the subpopulation of cells is analyzed while they are trapped within the purification device.

A particle filtering device which shortens the separation time of particles and increases the separation efficiency are provided. The particle filtering device comprises: a filtration membrane which separates a particle by filtering a sample; a first body connected to an inlet side of the filtration membrane, which supplies the sample to the inlet side of the filtration membrane; and a second body connected to an outlet side of the filtration membrane, which accommodates a permeate whose particle is separated through the filtration membrane, wherein the particle filtering device has a structure in which the permeate is accommodated in advance between the second body and the outlet side of the filtration membrane.

Described herein are microfluidic devices and methods that can separate and concentrate particles in a sample.

A method for dissociating cell aggregates in an agitated reactor. The method comprises providing a cell culture comprising cell aggregates in the agitated reactor, contacting the cell aggregates with a dissociation reagent, generating a dissociation force in the agitated reactor and exposing the contacted cell aggregates to the generated dissociation force under conditions sufficient to dissociate the contacted cell aggregates. The method may be used in a process for passaging cells and/or generating dissociated differentiated cells from stem and/or progenitor cells.

A tissue dissociation device includes an inlet coupled to a first stage having a single channel having an upstream end and a downstream end; a plurality of serially arranged intermediate stages, wherein a first intermediate stage of the plurality is fluidically coupled to the downstream end of the first stage, and wherein each subsequent intermediate stage of the plurality has an increasing number of channels (with channels of smaller dimensions); and an outlet coupled to a last stage of the intermediate stages.

[Object]

To provide a vessel suitable for efficient culture and differentiation induction or the like of cells in the same vessel while reducing any contamination risk, and also to provide a cell culture vessel capable of ensuring provision of a flat culture surface over a wide range.

[Solving Means]

A vessel manufacturing method includes placing a bag-shaped, film-based vessel on a placement stage with concave portions formed on the stage, introducing fluid into the vessel placed on the stage, and pressing the vessel which is placed on the stage, by a pressing member while heating at least one of the stage and the pressing member. Meanwhile, a cell culture vessel includes a first vessel wall as a bottom wall and a second vessel wall. The first vessel wall is formed of a flat film having gas permeability. The second vessel wall is disposed in contact with a peripheral edge portion of the first vessel wall, and has a bulge shape protruding relative to the first vessel wall. The first vessel wall is flat at its section other than a region where the first vessel wall is in contact with at least a charge/discharge port.

Medical instrument includes a substrate, in which cells are in contact with or held on a surface of the substrate, and at least the surface of the substrate which holds the cells is formed of a fluorine-containing cyclic olefin polymer which contains a repeating structure unit represented by Formula (1),

##STR00001##

wherein in Formula (1), at least one of R.sup.1 to R.sup.4 is fluorine, an alkyl with 1 to 10 carbon atoms which contains fluorine, an alkoxy with 1 to 10 carbon atoms which contains fluorine, or an alkoxyalkyl with 2 to 10 carbon atoms which contains fluorine, R.sup.1 to R.sup.4 are selected from hydrogen and certain non-fluorinated groups when R.sup.1 to R.sup.4 do not contain fluorine, R.sup.1 to R.sup.4 may be the same as or different from each other, and R.sup.1 to R.sup.4 may be bonded to each other to form a cyclic structure.
