This antibody recognizes an antigen on human continuous blood endothelial cells which are fully differentiated. The antibody staining is restricted to endothelial cells and does not sta in 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.
Immunohistochemistry on Frozen sections: 2 μg/mL (1:200). Positive control: Human placenta. Does not react on routinely processed paraffin sections.

Store lyophilized at 2-8°C. After reconstitution store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing. Shelf life: one year from despatch.
The antigen is found in variable numbers on freshly isolated umbilical vein endotheli al 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 commercia lly available endothelial cell media apparently have no influence on the antigen expression.
