The Bioaim Human Angiopoietin-2 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of Angiopoietin-2 in human serum and plasma. An antibody specific for human Angiopoietin-2 was coated on a 96-well plate. Standards and samples are added to the wells and any Angiopoietin-2 present binds to the immobilized antibody. The wells are washed and biotinylated anti-human Angiopoietin-2 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of Angiopoietin-2 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Angiogenesis; inflammation;
Angiopoietin -2 (Angiopoietin -2 ) Background: Angiopoietins, Ang-1, Ang-2, and Ang-3 (mouse)/Ang-4 (human), are natural agonists or antagonists of the Tie-2 receptor tyrosine kinase and are important modulators of angiogenesis. Angiopoietin is part of a family of vascular growth factors that play a role in embryonic and postnatal angiogenesis. Angiopoietin signaling most directly corresponds with angiogenesis, the process by which new arteries and veins form from preexisting blood vessels. Angiogenesis proceeds through sprouting, endothelial cell migration, proliferation, and vessel destabilization and stabilization. They are responsible for assembling and disassembling the endothelial lining of blood vessels. Angiopoietin cytokines are involved with controlling microvascular permeability, vasodilation, and vasoconstriction by signaling smooth muscle cells surrounding vessels. Two domains characterize the angiopoietin family of proteins: an N-terminal coiled-coil domain that mediates homo-oligomerization, and a C-terminal fibrinogen-like domain that binds Tie-2.
