Weitere Details:: 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 (sprouting of new capillary vessels from pre-existing vasculature). Angiogenesis 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). Certain pathological conditions, such as tumor growth and diabetic retinopathy, also require angiogenesis. Angiogenin is a single polypeptide chain of 123aa (mol wt ~14kD) secreted by tumor cells. It is a potent inhibitor of neovascularization. It specifically binds to endothelial cells and elicits second messenger systems. It has ribonucleolytic activity and is 33% identical to pancreatic RNAse A. Applications: Suitable for use in ELISA and Neutalizion. Western Blot, though not tested, may potentially be used as an application. Other applications not tested. Recommended Dilution: ELISA: 0.5-2.0ug antibody and 10-50ng of control antigen/well. Neutralization: 100-200ug IgG neutralizes 50% activity of 1ug of Angiogenin. Neutralizes biological activity of recombinant human Angiogenin as measured by measurement of ribonucleolytic activity using tRNA. Optimal dilution determined by the researcher.
