Clone Number: EN4
Immunogen: Unknown or proprietery to MONOSAN and/or its suppliers
Concentration: 100 ug/ml
Storage buffer: PBS with 0.1% BSA and 0.02% sodium azide
Additional info: This antibody stains all human blood vessels including brain microvessels. Both large and small vessels are equally reactive. The EN4 antigen is preserved in endothelial cells in culture unlike the PAL-E antigen which is lost. It stains strongly murine fibroblasts transfected with the human CD31 gene. On surface-iodinated Jurkat T cells it recognizes the 130 kD CD31 antigen. EN4 also binds to guinea-pig and cat endothelium, but not to rabbit, bovine, sheep, dog, rat or mice endothelial cells. No other structures in the skin, heart, kidney, tonsils or spleen are stained with this antibody.
