Patent number: 9249220Abstract: 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.Type: GrantFiled: March 11, 2014Date of Patent: February 2, 2016Assignee: PHARMABCINE INC.Inventors: Jin-San Yoo, Weon-Sup Lee, Sang-Ryeol Shim, Mi-Hee Park, Jeong-Eun Kang, Do-Yun Kim, Joon-Chul Lee, Dong-Heon Lee, Too-Hyon Cho, Sam-Sook Sul, Young-Guen Kwon, Bo-Jeong Pyun, Kwi-Hwa Kim, Chae-Ok Yun, Nahm-Ju Kim, Jae-Won Jeon, Dong-Sup Lee, Young-Woo Park, Geun-Bae Rha, Hyun-Sook Jang, Hyeon-Mi Yoo, Sung-Woo Kim, Semi Kim, Sang-Seok Koh
