An isolated antibody or an antigen-binding fragment thereof having a specific binding affinity to an epitope located within the domain 1 or domain 3 of human vascular endothelial growth factor receptor 2 (VEGFR2; SEQ ID NO: 74) is disclosed. The epitope within the domain 3 of the VEGFR2 is located between amino acid residues 250 and 270 of SEQ ID NO: 74. Use of the antibody or antigen-binding fragment thereof in the manufacture of a medicament for inhibiting tumor growth, tumor angiogenesis, and/or inducing cancer cell cytotoxicity in a subject in need thereof is also disclosed. Also disclosed is a method of detecting the presence of VEGFR2 in a tumor vascular endothelial cell or a cancer cell in a biological sample.
