Title (EN) CELL-TRAPPING FILTER
(FR) FILTRE DE PIÉGEAGE DE CELLULES
(JA) 細胞捕捉フィルター
Abstract:
(EN) Provided is a cell-trapping filter which has a high cell-trapping efficiency and excellent water resistance. The cell-trapping filter comprises a base equipped with a mechanism for separating cells in accordance with size, wherein the base has, at least on the surface thereof, a layer constituted of a fluoropolymer which has units each having a biocompatible group and has a fluorine atom content of 5-60 mass% and a proportion P represented by the following equation of 0.1-5%. Proportion P = ((proportion (mass%) of units each having biocompatible group to all the units of the fluoropolymer)/(fluorine atom content (mass%) of the fluoropolymer))×1 00
(FR) La présente invention concerne un filtre de piégeage de cellules présentant une efficacité élevée de piégeage de cellules et une excellente résistance à l'eau. Le filtre de piégeage de cellules comprend une base munie d'un mécanisme de séparation des cellules en fonction de la taille. La base présente, au moins sur sa surface, une couche constituée d'un polymère fluoré qui possède des motifs ayant chacun un groupe biocompatible et qui présente une teneur en atome de fluor de 5 à 60 % en masse et une proportion P représentée par l'équation suivante de 0,1 à 5 %. Proportion P = ((proportion (% en masse) des motifs ayant chacun un groupe biocompatible par rapport à tous les motifs du polymère fluoré)/(teneur en atome de fluor (% en masse) du polymère fluoré)) x 100
(JA) 細胞の捕捉効率が高く、耐水性に優れる細胞捕捉フィルターの提供。 基材に、大きさによる細胞分離機構が設けられた細胞捕捉フィルターであって、生体親和性基を有する単位を有し、フッ素原子含有率が5~60質量%であり、かつ下式で表される割合Pが0.1~5%である含フッ素重合体から形成される層を、前記基材の少なくとも表面に有する細胞捕捉フィルター。 割合P=(含フッ素重合体の全単位に対する生体親和性基を有する単位の割合(質量%)/含フッ素重合体のフッ素原子含有率(質量%))×100
