Title:
CELL CULTURE SUBSTRATE
Document Type and Number:
Japanese Patent JP2007267673
Kind Code:
A
Abstract:
To provide a cell culture substrate inexpensive and capable of carrying out various sterilization treatments without trouble.
Zeta-potential of the surface of a polystyrene which is the cell culture substrate, is usually zero to positive charge in 10 mM of aqueous NaCl solution with 5.0-7.5 of pH, and the ζ-potential of the polystyrene is changed into negative charge by a UV irradiation treatment, etc. In culturing cells by using the cell culture substrate with ζ-potential modified into negative charge, the cells are clearly proliferated as compared to the cell culture using the cell culture substrate with a positive ζ-potential.
