General description
55 kDa
The remodelling of the primitive vasculature in mammals to form the mature cardiovascular system includes a number of factors directing endothelial cell development. Angiopoietin-1 (mouse and human Ang-1; 498aa with 98% identity) is an angiogenic secreted protein that interacts with the endothelial specific Tie-2 receptor. It is primarily expressed in developing endothelial cells. During embryonic dvevelopment, Ang-1 binds and induces tyrosine phosphorylation of Tie-2. Ang-1 appears to play a crucial role in mediating matrix and mesenchyme. It mediates blood vessel maturation and stability. Ang-1 may play a critical role in heart development. Ang-1 deficient mice mimic the phenotype exhibited by animals deficient in Tie-2. A homolog of Ang-1, termed Angiopoietin-2 (mouse and human Ang-2, 496aa with 85% identity) may act as an antagonist for Ang-1 and Tie-2. Ang-1 and Ang-2 have ~60% sequence homology.

This Anti-Angiopoietin-1 Antibody, N-terminus is validated for use in ELISA, WB for the detection of Angiopoietin-1.
Western blot: 1-10 ug/mL using ECL. Expected size of Ang-1 is ~55kDa.
ELISA: 1:10,000-1:100,000 using 50-100 ng of control peptide per well (Catalog Number AG635).
Immunohistochemistry: Not tested. It is recommended that the antibody be used at 2-20 ug/ml in formaldehyde fixed tissue.
Optimal working dilutions must be determined by end user.
Biochem/physiol Actions
Recognizes mouse Angiopoietin-1 (Ang-1). The immunogenic peptide sequence is 90% (18/20 aa) conserved in human Ang-1, 95% I pig and bovine, and has no significant sequence homology with Ang-2. Antibody crossreactivity in other species is not established.
