Typical Testing Data/Standard Curve (for reference only)
Intended Uses: This ANG2 ELISA kit is intended for laboratory research use only. The stop solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of ANG2 in the sample, this ANG2 ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus ANG2 concentration. The concentration of in the samples is then determined by comparing the O.D. of the samples to the standard curve.
Principle of the Assay: The coated well immunoenzymatic assay for the quantitative measurement of ANG2 utilizes a polyclonal anti-ANG2 antibody and an ANG2-HRP conjugate. The assay sample and buffer are incubated together with ANG2-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the ANG2 concentration since ANG2 from samples and ANG2-HRP conjugate compete for the anti-ANG2 antibody binding site. Since the number of sites is limited, as more sites are occupied by ANG2 from the sample, fewer sites are left to bind ANG2-HRP conjugate. Standards of known ANG2 concentrations are run concurrently with the samples being assayed and a standard curve is plotted relating the intensity of the color (O.D.) to the concentration of ANG2. The ANG2 concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is an antagonist of angiopoietin 1 (ANGPT1) and endothelial TEK tyrosine kinase (TIE-2, TEK). The encoded protein disrupts the vascular remodeling ability of ANGPT1 and may induce endothelial cell apoptosis. Three transcript variants encoding three different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
Uniprot Description
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.

Product Notes
The Rabbit ANXA1 angpt2 (Catalog #AAA729994) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA729994 ELISA Kit recognizes Rabbit ANXA1. It is sometimes possible for the material contained within the vial of "Annexin A1, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
