title: Monoclonal antibodies against vascular endothelial growth factor 165 (VEGF165): neutralization of biological activity and recognition of the epitope.
abstract: Five antibodies against vascular endothelial growth factor 165 (VEGF165) were obtained. These antibodies, Ab-2, Ab-20, Ab-153, Ab-309, Ab-342, were able to recognize not only native VEGF165, but also reducing VEGF165. Three of the antibodies, Ab-153, Ab-309, Ab-342, were identified as VEGF165 neutralizing antibody on the basis of its ability to inhibit the proliferation of human umbilical vein endothelial cells (HUVEC) induced by VEGF165 and the binding of [125I]-VEGF165 to receptors on HUVEC. The fragments of E1 (VEGF120-135) and E2 (VEGF46-60) recognized by neutralizing antibodies may be related the receptor binding domain of VEGF.
