STORAGE CONTAINER FOR CELL-CONTAINING SOLUTION AND STORAGE SOLUTION

Provided, is a storage container for cell-containing solutions, which makes it possible to enhance the storage stability of cfDNA contained in a cell-containing solution even when the cell-containing solution is stored under a room temperature environment. The storage container for cell-containing solutions according to the present invention is intended to be used for storing a predetermined amount of a cell-containing solution, the storage container being provided with a container main body and a preservative solution contained in the container main body, in which the storage container has a first configuration such that the preservative solution contains a cell-membrane-permeable compound that has a molecular weight of 100 or less and cannot be frozen at 0°C and, when a mixed solution X is prepared by collecting the predetermined amount of the cell-containing solution in the storage container for cell-containing solutions and mixing the cell-containing solution with the preservative solution, the content of the cell-membrane-permeable compound in the mixed solution X is 1 vol% to 5 vol% inclusive, or the storage container has a second configuration such that the preservative solution contains a cell-membrane-impermeable compound having a molecular weight of 300 or more and, when a mixed solution X is prepared by collecting the predetermined amount of the cell-containing solution in the storage container for cell-containing solutions and mixing the cell-containing solution with the preservative solution, the content of the cell-membrane-impermeable compound in the mixed solution X is 0.5 µmol/L to 5 µmol/L inclusive. Il est décrit un contenant de stockage pour solutions contenant des cellules, ce qui permet d'améliorer la stabilité de stockage de l'ADN acellulaire contenu dans une solution contenant des cellules, même lorsque la solution contenant des cellules est stockée dans un environnement à température ambiante. Le conteneur de stockage de solutions cellulaires selon la présente invention est destiné à être utilisé pour stocker une quantité prédéterminée d'une solution cellulaire, le conteneur de stockage étant muni d'un corps principal du conteneur et d'une solution de conservation contenue dans le corps principal du conteneur, dans lequel le récipient de stockage présente une première configuration telle que la solution de conservateur contienne un composé perméable à membrane cellulaire dont le poids moléculaire est égal ou inférieur à 100 et qui
