ANGPT2 is a secreted factor on the angiopoietin/Tie (tyrosine kinase with Ig and EGF homology domains) signaling pathway and is involved in tumor angiogenesis. In the presence of ANGPT1, ANGPT2 antagonizes ANGPT1-mediated Tie2 phosphorylation, leading to vessel sprouting or degeneration depending on the level of VEGF-A. Overexpression or inhibition of ANGPT2 increases or decreases angiogenic capacity, respectively. Angiopoietin-2 Protein, Cynomolgus/Rhesus Macaque (HEK293, hFc) is the recombinant Rhesus Macaque-derived Angiopoietin-2 protein, expressed by HEK293 , with C-hFc labeled tag.
