NOVEL GRAFT POLYMER, TEMPERATURE-RESPONSIVE SUBSTRATE FOR CELL CULTURE USING SAME AND PRODUCTION METHOD THEREFOR, AND LIQUID CHROMATOGRAPHY CARRIER HAVING IMMOBILIZED NOVEL GRAFT POLYMER AND LIQUID CHROMATOGRAPHY METHOD USING SAME
NOVEL GRAFT POLYMER, TEMPERATURE-RESPONSIVE SUBSTRATE FOR CELL CULTURE USING SAME AND PRODUCTION METHOD THEREFOR, AND LIQUID CHROMATOGRAPHY CARRIER HAVING IMMOBILIZED NOVEL GRAFT POLYMER AND LIQUID CHROMATOGRAPHY METHOD USING SAME
By using a graft polymer comprising a dendritic polymer with a styrene skeleton and a hydrophilic polymer grafted to a terminal thereof, a temperature-responsive substrate for cell culture having a temperature-responsive surface for cell culture that allows cells to be cultured with high efficiency and which yet allows cultured cells to be exfoliated in a short period of time and with high efficiency by simply changing the temperature of the substrate surface can be prepared conveniently. If this temperature-responsive substrate for cell culture is used, cells obtained from a variety of tissues can be cultured with high efficiency. If this culture method is utilized, cultured cells can be exfoliated intact in a short amount of time with high efficiency. In addition, by using this graft polymer, a wide range of peptides and proteins can also be separated by simply changing the temperature of a chromatographic carrier. This allows for convenient separation procedure and improves the efficiency of separating operations. What is more, the stereoregularity of the dendritic polymer per se may be utilized to enable separation of solutes based on differences in their molecular structures.
