Catalog no. :  RKO15123



Optimized DNA sequence  encoding  extracellular domain of Human Angiopoietin-2 including a C-terminal His tag was expressed in HEK293 cells. 

Molecular weight:

Recombinant Angpt2 is a  protein consisting of 490 amino acid residue subunits,  due to glycosylation migrates as an approximately 70kDa protein on SDS-PAGE.

>97%, as determined by SDS-PAGE and HPLC
Biological Activity:
The activity was tested by the ability of immobilized recombinant Human Tie2 to bind biotinylated recombinant human Angiopoietin-2 in ELISA

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant Human Angiopoietin-2  is lyophilized from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

Recombinant Angiopoietin-2 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

Angiopoietin-2 (Ang2)2 is a 70-kDa secreted ligand whose increased expression has been implicated in a range of diseases, including cancer, sepsis, and acute respiratory distress syndrome. The primary receptor for Ang2 is the transmembrane tyrosine kinase Tie2 (3) that is expressed mainly on vascular endothelial cells and myeloid cells (1, 4). Ang2 plays an important role in vascular remodeling during development, but in adult tissues, Ang2 concentrations are usually low. An increase in Ang2 levels in disease allows the molecule to compete for binding to a common interface on Tie2 with the related agonist Ang1.
