Natural and recombinant mouse Angiopoietin-2

Store at 4 degree C for 6 months, at -20 degree C for 12 months. Avoid multiple freeze-thaw cycles (Shipped with wet ice.)

Samples: Cell culture supernates, serum and plasma (heparin, EDTA). Assay Type: Sandwich. Detection Range: 156pg/ml-10,000pg/ml. Sensitivity: < 10pg/ml

Intra-assay Precision: Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision. Inter-assay Precision: Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Principle of the assay: mouse Angiopoietin-2 ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for Angiopoietin-2 has been precoated onto 96-well plates. Standards(CHO, M1-F496) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Angiopoietin-2 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB are used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse Angiopoietin-2 amount of sample captured in plate. Background: Angiopoietin-2 is a protein that in humans is encoded by the ANGPTL2 gene. Angiopoietins are members of the vascular endothelial growth factor family and the only known growth factors largely specific for vascular endothelium. Angiopoietin-1, angiopoietin-2, and angiopoietin-4 participate in the formation of blood vessels. Human and mouse ANGPT2 are 85% identical in amino acid sequence and approximately 60% identical to their ANGPT1 homologs. Transgenic overexpression of ANGPT2 in mice disrupted blood vessel formation in the mouse embryo. By FISH and radiation hybrid analysis, the human ANGPT2 gene was mapped to 8p23, and in a region of syntenic homology on mouse chromosome 8, where the Angpt2 gene was mapped. ANGPT2 is a naturally occurring antagonist of angiopoietin-1 that competes for binding to the TIE2 receptor and blocks ANGPT1-induced TIE2 autophosphorylation during vasculogenesis.

This gene encodes an endothelial cell (EC)-derived regulator of angiogenesis and ligand for endothelial-specific receptor tyrosine kinase. The encoded protein acts as an anti-apoptotic factor for stressed ECs and a proapoptotic factor for resting ECs. [provided by RefSeq, Jan 2013]

ANGPT2: 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. Interacts with TEK/TIE2, competing for the same binding site as ANGPT1. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Secreted; Secreted, signal peptide. Cellular Component: extracellular space; cell projection; extracellular region; plasma membrane; nucleus.
