INTRODUCTION
ANGPT2 aka Angiopoietin-2 competes for binding to the TIE2 receptor and blocks angiopoietin-1 aka ANGPT1 induced TIE2 autophosphorylation during vasculogenesis. ANGPT-2 is a naturally occurring antagonist of ANGPT-1. ANGPT2 induces tyrosine phosphorylation of TEK/TIE2 in the lack of Angiopoietin-2. In the deficiency of VEGF an angiogenic inducer, ANGPT-2 induces endothelial cell apoptosis resulting in vascular regression. ANGPT2 along with VEGF enable endothelial cell migration and proliferation, resulting in permissive angiogenic signal.
DESCRIPTION
ANGPT2 produced in Chinese hamster ovary (CHO) cells by recombinant DNA technology is a single, polypeptide chain (19-496 a.a.) and fused to a 6 aa His Tag at C-terminus containing a total of 484 amino acids and having a molecular mass of 55.7kDa.
ANGPT2 shows multiple bands between 50-100kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
