General description

TIE2 (tyrosine kinase with Ig and EGF homology domains 2) is expressed almost exclusively in endothelial cells in mice, rats and humans. This receptor possesses a unique extracellular domain containing two immunoglobulin-like loops separated by three epidermal growth factor-like repeats that are connected to three fibronectin type III-like repeats. The ligand for the receptor is Angiopoietin 1. Defects in TIE2 are associated with inherited venous malformations; the TIE2 signaling pathway appears to be critical for endothelial cell-smooth muscle cell communication in venous morphogenesis.

Specificity

Recognizes Tie2/TEK, Mr 145kDa

Immunogen

Fusion protein corresponding to residues 1-745 of human Tie2/TEK with a C-terminal His6-tag purified from infected SF-9 cells. Clone Ab33

Application

Immunoprecipitation: This antibody immunoprecipitated Tie2/TEK, as reported by an independent laboratory.

Immunohistochemistry: Reported to detect Tie2/TEK in frozen, Triton-treated sections.
This antibody is not suitable for paraffin-embedded sections.
This Anti-Tie2/TEK Antibody, clone Ab33 is validated for use in WB, IP, IH for the detection of Tie2/TEK.

Quality

Evaluated by western blot on RIPA lysates from HUVEC cells.

Western Blot Analysis: 0.2-1 μg/mL of this antibody detected Tie2/TEK in RIPA lysates from HUVEC cells.

Target description

145 kDa
