Title (EN) TEMPERATURE-RESPONSIVE CELL CULTURE SUBSTRATE
(FR) SUBSTRAT DE CULTURE CELLULAIRE THERMOSENSIBLE
(JA) 温度応答性細胞培養基材
Abstract:
(EN) A temperature-responsive cell culture substrate is provided which has better cell detachability and which suppresses elution of a temperature-responsive polymer during use. This temperature-responsive cell culture substrate has a temperature responsive layer (A), and the temperature-responsive layer (A) contains a temperature-responsive polymer. Of all the temperature-responsive polymers included in the temperature-responsive layer (A) that have a 4.0 or higher a common logarithm (log M) of the molecular weight (M), the total of temperature-responsive polymers that have a 5.5 or higher log M is greater than or equal to 60%.
(FR) L'invention concerne un substrat de culture cellulaire thermosensible qui présente une meilleure aptitude au détachement des cellules et qui supprime l'élution d'un polymère thermosensible pendant l'utilisation. Ce substrat de culture cellulaire thermosensible a une couche thermosensible (A), et la couche thermosensible (A) contient un polymère thermosensible. De tous les polymères thermosensibles inclus dans la couche thermosensible (A) qui ont un logarithme commun (log M) de 4.0 ou plus du poids moléculaire (M), le total des polymères thermosensibles qui ont un log M supérieur ou égal à 5,5 est supérieur ou égal à 60 %.
(JA) より優れた細胞剥離性を有し、かつ使用中の温度応答性ポリマーの溶出が抑制された温度応答性細胞培養基材を提供する。 温度応答性層(A)を有する温度応答性細胞培養基材であって、 前記温度応答性層(A)が温度応答性ポリマーを含み、 前記温度応答性層(A)に含まれる、分子量Mの常用対数(logM)が4.0以上である前記温度応答性ポリマーの合計のうち、logMが5.5以上である前記温度応答性ポリマーの合計が、60%以上である、 温度応答性細胞培養基材。
