IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Endostatin is a broad-spectrum angiogenesis inhibitor and may interfere with the pro-angiogenic action of growth factors such as basic fibroblast growth factor (bFGF/FGF-2) and vascular endothelial growth factor (VEGF). Collagen is a component of epithelial and endothelial basement membranes. Endostatin, as a fragment of collagen 18, demonstrates a role of the ECM in suppression of neoangiogenesis. Pro-angiogenic and anti-angiogenic factors can also be created by proteolysis during coagulation cascades. Endogenous inhibitors of angiogenesis are present in both normal tissue and cancerous tissue. Overall, endostatin down regulates many signaling cascades like ephrin, TNF-α, and NFκB signaling as well as coagulation and adhesion cascades. Diseases associated with COL18A1 include Knobloch Syndrome, Type 1 and Knobloch Syndrome.
