| 目标/特异性 | Detects mouse VEGF-B167 and mouse VEGF-B186 in direct ELISAs and Western blots. In direct ELISAs, approximately 40% cross-reactivity with rhVEGF-B186is observed, 15% cross-reactivity with rhVEGF-B167 is observed and less than 1% cross-reactivity with rmVEGF164, rhVEGF-C and rmVEGF-D is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Blockade of Receptor-ligand Interaction: In a functional ELISA, 0.04-0.1 µg/mL of this antibody will block 50% of the binding of 5 ng/mL of Recombinant Mouse VEGF-B186 (Catalog # 767-VE) to immobilized Recombinant Human VEGF R1/Flt-1 Fc Chimera (Catalog # 321-FL) coated at 4 µg/mL (100 µL/well). This antibody can also block the binding of Recombinant Mouse VEGF-B167 (Catalog # 2595-VE) to immobilized Neuropilin‑1 Fc Chimera. |

| 背景 | Vascular endothelial growth factor B (VEGF-B; also known as VFR) is a member of the VEGF-PDGF supergene family of growth factor molecules (1 - 4). Five mouse members have been identified, including VEGF-A, -B, -C, -D, and PlGF(-2) (1, 5). VEGF family members are disulfide-linked homo- and heterodimeric proteins that are important regulators of vasculogenesis and lymphangiogenesis. Mouse VEGF-B has two isoforms, a 32 kDa single chain and a 21 kDa single chain form (6, 7). The long form (VEGF-B186) is 207 amino acids (aa) in length, with a 21 aa signal sequence and a 186 aa mature region. The short form (VEGF-B167) is 188 aa in length, with a 21 aa signal sequence and a 167 aa mature segment. Each mature isoform shows the same N-terminal 94 aa that contains a cysteine knot VEGF homology domain (6 - 8). VEGF-B186 is O-glycosylated; VEGF-B167 is not. VEGF-B167 binds heparin; VEGF-B186 does not. Thus, VEGF-B186 is secreted and freely diffusible in tissues (7). However, the VEGF-B167 isoform is the predominant form in tissue (9). Mouse VEGF-B186 is 93% and 87% aa identical to bovine and human VEGF-B186, respectively; mouse VEGF-B167 is 90% and 88% aa identical to bovine and human VEGF-B167, respectively. The mouse VEGF-B167 homodimer is 42 kDa in size, while the VEGF-B186 homodimer is 62 kDa in size. Unlike VEGF167, VEGF-B186 undergoes proteolytic processing that creates a partially processed 48 kDa homodimer and a fully processed 32 kDa homodimer. Processing appears to occur at Arg127 of the mature form (10). Both forms of VEGF-B can heterodimerize with VEGF (7). Both VEGF-B isoforms bind to VEGF receptor 1 (VEGF R1), but not VEGF R2 or VEGF R3 (11). VEGF-B167 also binds neuropilin-1, but only the 127 aa processed form of VEGF-B186 binds neuropilin-1 (10). As a dimer, full length VEGF-B186 does not interact with neuropilin-1, while any dimer that contains the processed VEGF-B127 subunit will interact with neuropilin-1 (10). The importance of differential neuropilin binding is unclear. VEGF-B deficient mice display an atrial conduction deficit (12). On endothelial cells, ligation of VEGF R1 by VEGF-B has been shown to regulate the expression and activity of urokinase type plasminogen activator and plasminogen activator inhibitor 1 (11). |
