  • 产品描述:

    The product CSB-MP001707HU(A4) is a recombinant human angiopoietin-2(ANGPT2) protein expressed in mammalian cells. This protein carries a C-terminal 10xHis-tag. Its expression region encodes the 19-496aa of the human ANGPT2 protein. In the functional ELISA, this ANGPT2 protein binds to the anti-ANGPT2 recombinant antibody, with the EC50 of 0.6666-0.8876 ng/mL. This demonstrates that it is an active protein. It reached up to 92% in purity measured by SDS-PAGE. Its endotoxin level was determined to be less than 1.0 EU/ug using the LAL method.

    ANGPT2 is an angiogenesis factor that regulates endothelial cell differentiation, survival, and stability. It is mainly expressed in endothelial cells. As a natural competitive antagonist of ANGPT1, ANGPT2 competitively inhibits the TIE2 phosphorylation of ANGPT1. ANGPT2 can maintain the dynamic balance of blood vessel growth and degeneration by inhibiting the activation of ANGPT1. ANGPT2/TIE2 signaling pathway plays an important role in tumor angiogenesis, sprouting, persistence, and metastasis. A complementary pathway recently explored as a potential new drug target is the ANGPT2/TIE2 axis, which helps regulate vascular permeability and inflammation.

  • 功能:
    Binds to TEK/TIE2, competing for the ANGPT1 binding site, and modulating ANGPT1 signaling. Can induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, ANGPT2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, it may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal.
