Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gelatin aqueous composition that is quickly gelatinized at a temperature of 27°C or more and has the gel dissolved at about 32°C or more, and gelatin and the like for use therein, and a medical laminate using the gelatin aqueous composition, a method for producing the medical laminate and a method for separating a cell sheet.SOLUTION: The present invention provides gelatin with the content of a high molecular weight component of 10-50 mass%, and a value obtained by subtracting the content of a low-molecular weight component from the content of the high molecular weight component of 0 mass% or more, or a chemically modified body thereof.SELECTED DRAWING: Figure 1 【課題】２７℃以上の温度で急速にゲル化し、約３２℃以上でゲルが溶解するゼラチン水性組成物、およびそれに用いられるゼラチン等を提供すること、ならびに前記ゼラチン水性組成物を用いる医療用積層体、その医療用積層体の製造方法および細胞シートの単離方法を提供すること。【解決手段】高分子量成分の含有量が１０〜５０質量％であり、高分子量成分の含有量から低分子量成分の含有量を差し引いた値が０質量％以上であるゼラチンまたはその化学修飾体。【選択図】図１
