Product Info
Background The vascular endothelial growth factor (VEGF) family currently includes VEGF (VEGF-A), VEGF-B, VEGF-C, VEGF-D, VEGF-E, and PIGF (1). VEGF and its receptor system have been shown to be the fundamental regulators in the cell signaling of angiogenesis (2). Most tumors have the absolute requirement of angiogenesis and VEGF has been described as the most potent angiogenic cytokine linked to this process (3&4). To date 5 different isoforms of VEGF have been described, VEGF 121, VEGF 145, VEGF 165, VEGF 165b, and VEGF 189(4&5). These isoforms are generated as the result of alternative splicing from a single VEGF gene. These various isoforms have been shown to bind to two tyrosine-kinase receptors flt-1 (VEGFR-1) and flk-1/KDR (VEGFR-2), which have been found to be expressed almost exclusively on endothelial cells (5). 
Origin VEGF (A19) is provided as an affinity purified rabbit polyclonal antibody, raised against a peptide mapping to a domain near the amino terminus of Human VEGF. 
Product Details Each vial contains 200 g/ml of affinity purified rabbit IgG VEGF DB054 (A19), in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Competition Studies A blocking peptide is also available, DB054P, for use in competition studies. Each vial contains 0.100 mg of peptide in 0.5 ml PBS with 0.1% sodium azide and 100 mg BSA. 
Form 200 g/ml rabbit polyclonal IgG in 1 ml PBS containing 0.1 % sodium azide and 0.2% gelatin. 
Immunogen Synthetic peptide mapping to a domain near the amino terminus of Human VEGF. 
Specificity VEGF DB054 (A19) reacts with VEGF of Human origin 
Wester blot analysis of 0.5g of recombinant human VEGF.
