ABSTRACT:
A surface modification method of polysaccharide, the modified polysaccharide, and a method of culturing and recovery cells using the same are provided. The surface modification method of polysaccharide comprises (a) immersing a polysaccharide material in an acid, (b) immersing the polysaccharide material in an acidic solution containing a protein, and (c) immersing the polysaccharide material in an alkaline solution containing bivalent metal ions.
