Technical Data
Recent studies have identified several proteolytic fragments or cryptic domains of proteins that act as inhibitors of angiogenesis. These include fragments of plasminogen such as Angiostatin protein (kringles 1-4) and kringles 1-5, C-terminal proteolytic fragment of Collagen XVIII (Endostatin protein), the NC10 domain of collagen 15 (Restin), the C-terminal hemopexin-like domain of MMP-2 (PEX), the N-terminal fragment of prolactin, and the N-terminally truncated platelet factor. The 20kD fragment of Collagen XVIII known as Endostatin protein inhibits tumor progression and induction of endothelial cell apoptosis. Administration of Endostatin protein to mice bearing certain tumors caused tumor regression without the development of drug resistance. Endostatin protein also inhibited systemic angiogenesis, primary tumor growth, and the development of primary metastatic lesions. It also reduced the levels of antiapoptotic proteins Bcl-2 and Bcl-xL and an increase in apoptosis of endothelial cells. in vitro.

Suitable for use in Western Blot and ELISA. Other applications not tested.

Recommended Dilution:
Western Blot:1-10ug/ml using Chemiluminescence technique. Human and mouse endostatins are ~ 20kD.
ELISA:1:10K-1:100K; using 50-100 ng of control peptide/well
Optimal dilution determined by the researcher.
