Product Overview
This rabbit polyclonal antibody detects angiopoietin-2 (gene ANGPT2) in human samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 56.9 kDa, and the supplier reports an observed band at about 70 kDa.
Angiopoietin-2 (ANGPT2) is a TIE2 (TEK) ligand that competes with angiopoietin-1 and often acts as a context-dependent antagonist. It loosens vessel stability, promoting sprouting when VEGF is present and vessel regression when it is not, and it is widely studied in tumor angiogenesis, inflammation and vascular leakage.

Samples with a confirmed band (WB): human HepG2 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human lung cancer tissue, human placenta tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Immunogen
Recombinant human Angiopoietin-2 fragment (Glu180–Asp283), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 75% and 77.9%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes angiopoietin-2 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
