Abstract:
PROBLEM TO BE SOLVED: To obtain a supporting material for cell culture capable of peeling cultured cells by temperature change by coating the surface of a transparent plastic substrate with a solution produced by dissolving a temperature-sensitive polymer in a mixture of a good solvent of the plastic and a poor solvent and drying the applied solution. SOLUTION: The objective supporting material for cell culture enabling easy peeling of the cultured cell by temperature change is produced in high efficiency by coating a surface of a cell culture supporting material made of a transparent plastic (e.g. polystyrene) with 0.1-5.0mg/cm of a polymer solution produced by dissolving a temperature-sensitive polymer (e.g. poly-N-substituted- acrylamide) in a mixed solvent consisting of a solvent dissolving the plastic (e.g. toluene) and a solvent unable to dissolve the plastic (e.g. butanol), drying the applied solution by leaving standing at room temperature for 24hr to fix the polymer to the surface of the supporting material and washing the surface of the supporting material with chilled water.
