Angiopoietin-2 Antibody (748246)

Western blot shows lysates of mouse placenta tissue, mouse uterus tissue, and mouse ovary tissue. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse Angiopoietin-2 Monoclonal Antibody (Catalog # MAB7186) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Angiopoietin-2 at approximately 68 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Angiopoietin-2 Antibody (748246) Summary

• Immunogen: Chinese hamster ovary cell line CHO-derived recombinant mouse Angiopoietin-2
  Asp68-Phe496
  Accession # O35608
• Specificity: Detects mouse Angiopoietin-2 in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross‑reactivity with recombinant mouse (rm) Angiopoietin‑1, rmAngiopoietin-3, recombinant human (rh) Angiopoietin‑2, and rhAngiopoietin-4 is observed. In Western blots, 100% cross‑reactivity with rmAngiopoietin-1 is observed and less than 10% cross‑reactivity with rhAngiopoietin-2, rhAngiopoietin-4, and rmAngiopoietin-3 is observed.

Background

Angiopoietin-2 (Ang-2; also ANGPT2) is a secreted 66-70 kDa glycoprotein member of the angiopoietin family of growth factors. It is expressed by endothelial cells, macrophages and skeletal muscle fibers, and binds to the Tie2 receptor on select cell types, including endothelial cells and monocytes. Ang-2 has multiple functions. In the presence of growth factors, it promotes angiogenesis; in the absence of growth factors, it induces vascular regression. It is generally considered to be an antagonist of Ang-1 activity. Mature mouse Ang-2 is 478 amino acids (aa) in length (aa 19-496). It contains one coiled-coil region (aa 159-256) plus a C-terminal Fibrinogen-like domain (aa 275-495). Mouse Ang-2 undergoes covalent oligomerization, forming 140 kDa homodimers and 280 kDa homotetramers. The higher-order oligomers are strong Tie-2 agonists. Over aa 68-496, mouse Ang-2 shares 87% and 96% aa sequence identity with human and rat Ang-2, respectively.
