The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/200 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
1/250 - 1/500.
FunctionActs as a regulator of the antiangiogenic activity on endothelial cells. When overexpressed in endothelial cells, leads to inhibition of cell proliferation and migration and an increase in apoptosis. Inhibits melanoma growth When expressed in tumor-associated vasculature.
Tissue specificityExpressed in endothelial cells, colon and colon cancers. In the colon, expressed in the vasculature and muscularis mucosa. In colon cancer, strongly expressed in tumor stroma and the vasculature (at protein level). Expressed in ovarian epithelial cells. Down-regulated in ovarian cancer.
Sequence similaritiesBelongs to the FILIP1 family.
