Abstract
The application belongs to the technical field of biomedicines and provides an improved anti-Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) monoclonal antibody and an application thereof. By a computer-aided simulation design, a novel phage antibody library is designed, and an improved anti-VEGFR-2 monoclonal antibody is obtained after multiple rounds of screening. Both affinity and biological activity of the antibody are higher than those of an original antibody. The antibody is capable of effectively inhibiting combination of VEGFR-2 and a ligand Vascular Endothelial Growth Factor (VEGF) thereof in vitro, and may be used in treating a tumor and a disease caused by angiogenesis such as macular degeneration.
