Method for immobilizing a biomolecule on a solid substrate at a high density by using the substrate having an activated carboxyl group on a surface thereof and microarray produced using the method
Method for immobilizing a biomolecule on a solid substrate at a high density by using the substrate having an activated carboxyl group on a surface thereof and microarray produced using the method
Provided is a method for immobilizing a biomolecule on a solid substrate. The method includes coating the solid substrate with silane anhydride to introduce an anhydride functional group onto a surface of the solid substrate; obtaining a carboxyl group from the anhydride functional group by hydrolysis; reacting the carboxyl group with carbodiimide and succinimide to activate the carboxyl group; and contacting the biomolecule with the solid substrate having the activated carboxyl group on its surface to immobilize the biomolecule on the solid substrate.
