Figure 4From: Fas induces apoptosis in human coronary artery endothelial cells in vitroIdentification of Fas antigen in human coronary artery endothelial cells. Cell lysates were prepared from cultured HCAEC and were analyzed by western blotting with the same anti-Fas monoclonal antibody used for receptor activation in Figure 3. Note single major immunoreactive band (arrowhead). STD = molecular mass standards in kDa.Back to article page
