EDC is a heterobifunctional, water-soluble, zero-length carbodiimide crosslinker that is used to couple carboxyl groups to primary amines. EDC activates carboxyl groups first and forms amine reactive O-acylisourea imtermediate that spontaneously reacts with primary amines to form an amide bond and isourea by-product.
The unstable nature of the intermediate in aqueous solutions makes 2-step coupling, however in conjunction with N-hydroxysuccinimide, a 2-step coupling is possible.
EDC is ideal for peptide immobilization and hapten-carrier protein conjugation.
