摘要:
To enable accurate counting the number of cultured cells without pulling apart cell clusters even if cells are aggregated densely to form three-dimensional cell clusters. An image of cultured cells is acquired, and from this image, an image of cell clusters and an image of individual cells are separated. Based on each of the image of cell clusters and the image of individual cells, the number of cells in the cell cluster and the number of individual cells are calculated.

Provided are a multilayer film having excellent gas permeability and excellent handling properties and hence is suited for forming a cell culture container, and a cell culture container formed by using the same.A multilayer film used for forming a cell culture container, comprising: a base material composed of a polyethylene-based resin having a density of 0.87 g/cm3 to 0.90 g/cm3; and an inner layer composed of a polyethylene-based resin having a density of 0.896 g/cm3 to 0.93 g/cm3 and forming a cell culture icy surface. A cell culture container is formed by using this multilayer film.

A culture medium for animal cells for enhancing a metabolism activity of the TCA cycle (tricarboxylic acid cycle) in respiration of the animal cells includes, as effective components, amino acids metabolized to succinyl CoA that is an element constituting the TCA cycle at a concentration of 2.3 mmol/L to 6.0 mmol/L.
摘要:
A method for collecting cells that have been cultured by using a cell culture kit in which, at least, a culture container for cultivating cells, a cell collection container for collecting cells after cultivation and a waste liquid container for collecting a culture medium after cultivation are linked to one another through a conduit is provided. The method includes transferring a culture supernatant that has been cultured from the culture container to the waste liquid container, transferring a concentrated suspension of cells from the culture container to the cell collection container, returning part of the culture supernatant discharged in the waste liquid container to the culture container and allowing cells remaining in the culture container to be suspended in a suspension of cells, and transferring again a suspension of cells in which remaining cells are suspended from the culture container to the cell collection container.

Bubbles are removed from an observation area when observing the inside of a container that is made of a soft package material and encloses a liquid containing bubbles. Provided is a method in which, when observing the inside of a container that is made of a soft package material and encloses a liquid that contains bubbles, a part of space in the container is set to be an observation area, and the bubbles are pushed outside the observation area by pressing from above a part of the upper surface of the container that is positioned above the observation area by means of a pressing member and by moving the pressing member.
