Affinity Maturation for Antibody Engineering: The Critical Role of Residues on CDR Loops of Antibodies in Antigen Binding

Abstract excerpt

During the course of affinity maturation, antibodies exhibit enhanced antigen-binding affinities by altering the amino acids in their variable regions. Understanding the structural basis of these antibodies can be beneficial for antibody engineering. We determined the crystal structures of single-chain Fv (scFv) antibodies against (4-hydroxy-3-nitrophenyl)acetyl, C6 and E11, which had undergone affinity...
