Angiopoietin 2 (Ang-2, AGPT2, ANGPT2, Ang2)

Angiopoietin-1 is an angiogenic secreted protein that interacts with endothelial specific Tie-2 receptor. It is primarily expressed in developing endothelial cells. During embryonic development, Ang-1 binds and induces tyrosine phosphorylation of Tie-2. Ang-1 may play a critical role in heart development. A homolog of Ang-1, termed Angiopoietin-2 (mouse and human Ang-2, 496 AA; ~85% identity) has recently been identified. It may act as an antagonist for Ang-1 and Tie-2. Ang-1 and Ang-2 have ~60% sequence homology. It is prominently expressed in tissues that are in involved in vascular remodeling (ovary, placenta, and uterus).\n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nELISA: 1:10,000-1:100,000 (50-100ng of control peptide/well)\nWestern Blot: 1:1000-1:5000 (MW:~55kD)\nOptimal dilutions to be determined by the researcher.\n\nControl Peptide (ELISA): \nA2293-12\n\nStorage and Stability:\nLyophilized powder may be stored at 4 degrees C for short-term only. Reconstitute to nominal volume by adding sterile 40-50% glycerol and store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
