Abstract: The present invention relates to human monoclonal antibodies neutralizing vascular endothelial growth factor receptor and the use thereof. More specifically, relates to human ScFv molecules neutralizing vascular endothelial growth factor receptor, and a composition for inhibiting angiogenesis and a composition for treating cancer, which contain the human ScFv molecules. The disclosed monoclonal antibody neutralizing vascular endothelial growth factor receptor shows excellent neutralizing ability in living cells, compared to that of a commercially available antibody against vascular endothelial growth factor receptor, and shows the ability to neutralize vascular endothelial growth factor receptor not only in humans, but also in mice and rats. Thus, the monoclonal antibody will be useful in anticancer studies and will be highly effective in cancer treatment.
