    摘要： This invention provides a culture control method and a cell culture apparatus that enable stable cell culture by regulating shear stress to be applied to cells within an adequate range. With the application of such culture control method and cell culture apparatus, cell culture is performed under agitation culture conditions in which the shear stress distribution is 0.5 Pa to 20 Pa in 80% or more of the culture vessel by volume.

    摘要： A cell culture apparatus (1) of the present invention comprises: a culture vessel (2) in which a cell culture medium comprising at least one of culture components composed of a conjugate with a stimuli-responsive polymer is stored and cells are cultured in the medium; a stimulus-applying mechanism (4) that applies a predetermined stimulus to the conjugate so as to induce a predetermined change of the stimuli-responsive polymer in response to the stimulus; and, a separation mechanism (5) that separates at least a part of the medium components except for the conjugate from the cell culture medium, while leaving the conjugate in the cell culture medium, on the basis of a property change of the stimuli-responsive polymer.

    摘要： An adsorbent of the present invention includes a support; and a protein having an adsorption site for adsorbing a target substance, in which the protein includes a reversible binding site and a covalent binding site, the support includes an orientation-controlling site forming a reversible bond with the reversible binding site, and an immobilization site forming a covalent bond with the covalent binding site, the covalent binding site includes a nucleophilic functional group, and the immobilization site includes a functional group capable of reacting with the nucleophilic functional group by a nucleophilic substitution or a nucleophilic addition. Thus, it is possible to provide an adsorbent in which the utilization efficiency of the adsorption site of the protein is improved. As a result, the protein amount can be reduced, and the step for storing a culture solution can be simplified due to the faster purification step.

    摘要： A method and apparatus for screening of cell lines and culture conditions includes a target value setting step that sets a target value relating to a metabolic reaction of a culture cell; a first culturing step; an analysis step; an analysis value calculation step that performs a metabolism analysis based on an analysis result from the analysis step and calculates an analysis value; a culture condition computation step that computes, using a correlation model, a culture condition giving an analysis value most close to the target value, and modifies the culture condition set in the first culturing step to the computed culture condition; a second culturing step that cultures a cell under the modified culture condition; and a screening step.

    摘要： The present invention pertains to a means and method for, from a mixture (cell culture) of cells, a medium component, and a useful substance, recovering the first two using a single process. Specifically, the present invention pertains to a polypeptide modified with a stimulus-responsive polymer, characterized in that the stimulus-responsive polymer responds to a stimulus to induce a change in the physical properties of the modified polypeptide overall, and the change is reversible or pseudo-reversible.
