Beschreibung
Zusammenfassung:	The present invention provides a protein aggregation inhibitor which can suppress protein aggregation, even if the protein is heated, and can suppress decreases in protein activity, even if the protein is further heated, the protein aggregation inhibitor characterized by comprising a sulfobetaine polymer resulting from polymerizing a monomer component comprising a sulfobetaine monomer representedby formula (I). (In the formula, R1 represents a hydrogen atom or a methyl group, R2 represents an alkylene group having 1 to 4 carbon atoms, R3 represents an alkyl group having 1 to 4 carbon atoms, R4 represents an alkylene group having 1 to 4 carbon atoms, and X represents an -NH- group or an -O- group.) 本发明提供即使在蛋白质被加热的情况下也能够抑制蛋白质的凝聚、并且即使在蛋白质被加热的情况下也能够抑制蛋白质的活性降低的蛋白质凝聚抑制剂，其中，该蛋白质凝聚抑制剂含有使包含式(I)所示的磺基甜菜碱单体的单体成分聚合而成的磺基甜菜碱聚合物(式(I)中，R表示氢原子或甲基，R表示碳原子数1～4的亚烷基，R表示碳原子数1～4的烷基，R表示碳原子数1～4的亚烷基，X表示-NH-基或-O-基)。
