Abstract
The present invention belongs to the field of tumor immunotherapy, and relates to a humanized monoclonal antibody that binds to VEGF. The present invention discloses nucleic acid sequences (including heavy/light chain variable regions) encoding said antibodies, and vectors, pharmaceutical compositions and kits containing said nucleic acid sequences. The antibody disclosed in the present invention can specifically bind to VEGF with high affinity and block the binding of VEGF to the receptor VEGFR2. Said antibodies also neutralize the proliferative effect of VEGF165 protein and multiple VEGF subtypes on HUVEC cells and can be used in clinical treatment of tumors, including but not limited to: colorectal cancer.
