Immobilized antibodies.

摘要

An immobilized antibody is provided by covalently bonding antibody on the surface of glass activated by introducing thereon a reactive group such as a thiol, hydroxyl, carboxyl, or, preferably, amino group. Usually, the covalent bonding is via a crosslinking agent, especially a maleimide. The immobilized antibody can be employed in immunoassays and the used immobilized antibody can be reused repeatedly after washing with dilute acid.
