<p>A chemically modified substrate with which DNAs can be efficiently explicated or stored and which is inexpensive and useful in the fields of molecular biology, biochemistry, etc.; and a method of chemical modification. The method is characterized by aminating a surface of a substrate and then carboxylating the surface with a treating fluid containing an anhydride of a polycarboxylic acid to thereby chemically modify the substrate.</p> |
