Zebrafish Tie-2 Antibody Summary

Species Reactivity

Zebrafish

Specificity

Detects zebrafish Tie-2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, no cross-reactivity with human or mouse Tie‑1 and Tie‑2 is observed.

Source

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

Mouse myeloma cell line NS0-derived recombinant zebrafish Tie-2
Val22-His741
Accession # O73791

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Label

Unconjugated

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Zebrafish Tie‑2 Fc Chimera (Catalog # 928-T2)

Blockade of Receptor-ligand Interaction

In a functional ELISA, 0.03-0.1 µg/mL of this antibody will block 50% of the binding of 25 ng/mL of Recombinant Human Angiopoietin-2 (Catalog # 623-AN) to immobilized Recombinant Zebrafish Tie-2 Fc Chimera (Catalog # 928‑T2) coated at 4 µg/mL (100 µL/well). At 0.5 μg/mL, this antibody will block >90% of the binding.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Angiopoietin-2 binding to Tie-2 blocked by Zebrafish Tie-2 Antibody. In a functional ELISA, Recombinant Human Angiopoietin-2 (Catalog # 623-AN) binds to immobilized Recombinant Zebrafish Tie-2 Fc Chimera (Catalog # 928-T2) coated at 4 µg/mL (100 µL/well) in a dose-dependent manner (orange line). Binding is blocked (green line) by increasing concentrations of Mouse Anti-Zebrafish Tie-2 Monoclonal Antibody (Catalog # MAB928). At 0.5 µg/mL, this antibody will block >90% of the binding.

Background: Tie-2

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.

Zebrafish Tie-2 cDNA encodes a 1116 amino acid (aa) residue precursor protein shares 38% sequence homology with human Tie-2 in the extracellular domain. Two ligands, angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2), which bind Tie-2 with high-affinity have been identified. Ang2 has been reported to act as an antagonist for Ang1. Mice engineered to overexpress Ang2 or to lack Ang1 or Tie-2 display similar angiogenesis defects.
