ペプチドおよびその自己集合方法、その集合体、これらを用いた細胞培養基材、並びに、細胞シートの製造方法

摘要

PROBLEM TO BE SOLVED: To provide a means for expressing coacervation (self assembling) capability in a peptide, even at a lower molecular weight.SOLUTION: The peptide (a) or (b) is provided in which (a) is a peptide expressed by chemical formula 1 [wherein, (n) is an integer of 4 to 300], and (b) is a peptide which is obtained by deleting, substituting and/or adding one or several amino acids in the peptide (a), and shows a temperature dependent self assembling property.
