Anti-Endostatin Antibody

Endostatin is a proteolytic cleavage product from the C-terminus of Collagen XVIII, which is itself a proteoglycan/collagen found in blood vessel walls and in basement membranes. Endostatin is a compact globular fold-containing protein with a Zn2+ binding site near its amino terminus. Originally identified in conditioned media of murine hemangioendothelioma (EOMA) cells, endostatin is generated from the parent collagen XVIII molecule involving intermediate glycosylated forms and the proteolytic activity of proteases such as cathepsin L, metalloproteases, and elastase. Endostatin has a wide-spread tissue expression and has been shown to co-localize with fibulins, nidogen-2 in basement membranes, and elastic fibers of veins. Endostatin has also been shown to cause a G1 arrest in endothelial cells and to induce apoptosis.

This antibody recognizes Endostatin at the nonhelical region 11 domain.
