Abstract
This structure constitutes a culture vessel having a plurality of accommodation sections in which cells are cultured. The structure comprises: a base that includes a plurality of through holes opening in the vertical direction; and an adherence layer which is provided on the bottom surface of the base and onto the bottom surface of which a sheet for closing the through holes is adhered. The adherence layer has openings that are located below the through holes and that have an outline greater than an outline of the through holes in plan view.
Claims20
A structural body constituting a culture vessel that includes a plurality of compartments for culturing cells, the structural body comprising:
- a base member including a plurality of through holes each opening in a vertical direction;
- and
- an attachment layer provided on a lower surface of the base member, the attachment layer attaching a sheet for closing the through hole to the lower surface, wherein
- the attachment layer includes, under the through hole, an opening whose outer shape is larger than an outer shape of the through hole in a plan view.
A structural body, comprising:
- a base member including a through hole or a recess;
- and
- a pressure-sensitive adhesive layer provided on one surface of the base member,
- wherein
- the structural body forms a vessel by adhering another base member or a sheet via the pressure-sensitive adhesive layer to close at least one surface of the through hole or close the recess, the vessel allowing observation of a biologically-derived substance, and
- a pressure-sensitive adhesive forming the pressure-sensitive adhesive layer has features below
- a residual rate of Rhodamine B in a solution is 20% or more, the solution being obtained by affixing a test piece of the pressure-sensitive adhesive cut to a size of 10 mm×10 mm to a bottom surface of a tissue culture-treated polystyrene well having an opening diameter of 16.2 mm, a well depth of 18 mm, and a well capacity of 3.5 mL, filling the well with 0.5 mL of a phosphate-buffered saline solution of the Rhodamine B at a concentration of 5 μM, and allowing the phosphate-buffered saline solution to stand at 23° C. for 48 hours, and
- a generated load when a dynamic strain of 0.05% is applied to the test piece of the pressure-sensitive adhesive by using a solid viscoelasticity measuring device is 20 g or less, the test piece having a width of 5 mm.
