Angiopoietin 1 (Agpt, ang1, Ang1, Ang-1, ANG-1, Angiopoietin-1)

Embryonic vascular system undergoes a series of complex, highly regulated series of events involving differentiation, migration and association of primitive endothelial cells. This process is termed vasculogenesis. A further remodeling of the primitive vascular system forms the mature cardiovascular system. This process is known as angiogenesis and it accounts for the formation of vasculature into previously avascular organs such as brain and kidney. Angiogenic activity in the adult is required during the normal tissue repair, and for the remodeling of the female reproductive organs (ovulation and placental development). Angiopoietin 1 (mouse and human: 498aa; ~98% identity) is an angiogenic secreted protein that interact with endothelial specific Tie-2 receptor. It is primarily expressed in developing endothelial cells. During embryonic development, Angiopoietin 1 binds and induces tyrosine phosphorylation of Tie-2. Angiopoietin 1 appears to play a crucial role in mediating matrix and mesenchyme. \n\nApplications: \nSuitable for use in ELISA, Immunohistochemistry and Western Blot.
