| 目标/特异性 | Detects human Tie-2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 20% cross-reactivity with recombinant mouse Tie-2 is observed and less than 1% cross-reactivity with recombinant human Tie-1 is observed. |
| 使用方法 | Western Blot: 1 µg/mL Simple Western: 10 µg/mL Immunohistochemistry: 5-15 µg/mL Blockade of Receptor-ligand Interaction: In a functional ELISA, 5-10 µg/mL of this antibody will block 50% of the binding of 40 ng/mL of biotinylated Recombinant Human Angiopoietin-2 (Catalog # BT623) to immobilized Recombinant Human Tie-2 Fc Chimera (Catalog # 313-TI) coated at 4 µg/mL (100 µL/well). At 50 μg/mL, this antibody will block >90% of the binding. |

| 背景 | Tie-1/Tie (tyrosine kinase with Ig and EGF homology domains 1) and Tie-2/Tek comprise a receptor tyrosine kinase (RTK) subfamily with unique structural characteristics: two immunoglobulin-like domains flanking three epidermal growth factor (EGF)-like domains and followed by three fibronectin type III-like repeats in the extracellular region and a split tyrosine kinase domain in the cytoplasmic region. These receptors are expressed primarily on endothelial and hematopoietic progenitor cells and play critical roles in angiogenesis, vasculogenesis and hematopoiesis. Human Tie-2 cDNA encodes a 1124 amino acid (aa) residue precursor protein with an 18 residue putative signal peptide, a 727 residue extracellular domain and a 354 residue cytoplasmic domain. Two ligands, angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2), which bind Tie-2 with high-affinity have been identified. Ang-2 has been reported to act as an antagonist for Ang-1. Mice engineered to overexpress Ang-2 or to lack Ang-1 or Tie-2 display similar angiogenesis defects. |

Detection of Human Tie‑2 by Western Blot. Western blot shows lysate of HUVEC human umbilical vein endothelial cells. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Tie‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF313) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Tie‑2 at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Tie‑2 in Human Placenta. Tie‑2 was detected in immersion fixed paraffin-embedded sections of human placenta using Goat Anti-Human Tie‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF313) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human Tie‑2 by Simple WesternTM. Simple Western lane view shows lysates of HUVEC human umbilical vein endothelial cells, loaded at 0.2 mg/mL. A specific band was detected for Tie‑2 at approximately 161 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Tie‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF313) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
