Product details:
Mouse Angiopoietin 2 ELISA Kit (ab209883) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Angiopoietin 2 protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse Angiopoietin 2 with 17.3 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Angiopoietin 2 is a secreted glycosylated protein functioning in angiogenesis, inflammation and vascular development. Angiopoietin 2 binds to receptor tyrosine kinase TEK/TIE2, competing for the ANGPT1 binding site, and modulating ANGPT1 signalling. Angiopoietin 2 can induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, Angiopoietin 2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, Angiopoietin 2 may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal.

Angiopoietin-2 also known as ANG2 or ANGPT2 is a glycoprotein with a molecular mass of approximately 70 kDa. It plays an important role in angiogenesis facilitating blood vessel remodeling and maturation. The protein is mainly expressed in endothelial cells where it functions by binding to the Tie2 receptor partially disrupting the Angiopoietin-Tie2 signaling axis. This disruption modulates vascular stability and permeability. The lyophilized form of the ANG-2 protein is often used in research for functional assays like ANG-2 ELISA to quantify its levels in various biological samples.
Biological function summary
Human angiogenesis processes are significantly affected by Angiopoietin-2 which serves as an antagonist to Angiopoietin-1 in regulating vascular dynamics. Although it does not form a stable complex by itself ANG2 activity is closely linked to its interactions with the Tie2 receptor modulating signal pathways that govern endothelial cell survival and permeability. Because of its dual role either stabilizing or destabilizing blood vessels under different conditions ANG2 serves as an important regulator during both normal physiological events and pathophysiological conditions.
Pathways
Angiopoietin-2 significantly contributes to the angiogenesis signaling network. It is deeply involved in the VEGF (Vascular Endothelial Growth Factor) pathway where ANG2 acts to balance VEGF activities in angiogenesis and vessel permeability. The interplay between Angiopoietin-2 and other proteins such as Angiopoietin-1 which stabilizes the vessels is vital for the precise regulation of blood vessel homeostasis during normal and disturbed conditions.
Angiopoietin-2 has a prominent role in the pathology of diseases like cancer and diabetic retinopathy. In cancer excessive ANG2 expression may lead to increased tumor angiogenesis and metastasis making it a target for cancer therapies. In diabetic retinopathy elevated levels of ANG2 correlate with vascular leakage contributing to disease progression. The relationship between Angiopoietin-1 and Angiopoietin-2 in these conditions emphasizes their collective impact on vascular anomalies associated with these disorders.
