Product Summary for Human Tie-2 Quantikine ELISA Kit
The Quantikine Human Tie-2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Tie-2 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human Tie-2 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Tie-2 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human Tie-2.

Background: Tie-2
Tie-2, also known as Tek, is a transmembrane receptor tyrosine kinase (RTK) that functions as a receptor for Angiopoietin family proteins. It is expressed by embryonic and adult endothelial cells, hematopoietic stem cells, and a circulating population of proangiogenic monocytes. Tie-2 signaling is activated by Angiopoietins-1 and -4, while it can be either activated or inhibited by Angiopoietins-2 and -3. Tie-2 plays an important role in maintaining vascular integrity by mediating endothelial cell-smooth muscle cell communication and inhibiting endothelial cell apoptosis. It is also required for embryonic development of the endocardium. In addition, Tie-2 signaling mediates the quiescence of bone marrow stem cells in response to osteoblast-produced Angiopoietin-1. This quiescence is critical for maintaining an ongoing hematopoietic capability in the bone marrow.
