Rat monoclonal [1F10] to Endothelial Cell (Biotin)
特異性ab51675 recognizes an antigen expressed on human continuous blood endothelial cells which are fully differentiated. The antibody staining is restricted to endothelial cells and does not stain any other cell in tissues or in peripheral blood. On sinusoidal endothelial cells of the liver or lymphatic organs the antigen is inconsistently expressed or absent.
On isolated cells, the antigen is found in variable numbers on freshly isolated umbilical vein endothelial cells (HUVECs). Antigen expression on cultured HUVECs is dependent on the culture conditions. Best results were obtained (40-70% pos.) by daily renewal of FCS containing medium supplemented with endothelial cell conditioned supernatant whereas commercially available endothelial cell media apparently have no influence
on the antigen expression.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml.
追加情報Is unsuitable for IHC-P.
関連性The endothelium is the layer of thin specialized epithelium, comprising a simple squamous layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall (simple squamous epithelium). Endothelial cells line the entire circulatory system, from the heart to the smallest capillary.
Endothelial cells are involved in many aspects of vascular biology, such as vasoconstriction and vasodilation, and hence the control of blood pressure; blood clotting (thrombosis & fibrinolysis); atherosclerosis; formation of new blood vessels (angiogenesis) and inflammation and swelling (oedema). Endothelial cells also control the passage of materials, and the transit of white blood cells, into and out of the bloodstream.
