Experimental details: Immunofluorescent analysis of Endothelin 1 (green) showing positive staining in the secretion of Hela cells (right) compared with a negative control in the absence of primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes, blocked with 3% BSA-PBS for 30 minutes at room temperature and probed with an Endothelin 1 monoclonal antibody (Product # MA3-005) in 3% BSA-PBS at a dilution of 1:200 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 488-conjugated goat-anti-mouse IgG (H+L) secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with DAPI for 5-10 minutes in the dark. Images were taken at a magnification of 60x.

Experimental details: Flow cytometry analysis of Endothelin 1 in 293T cells compared to an isotype control (blue). Cells were harvested, adjusted to a concentration of 1-5x10^6 cells/mL, fixed with 2% paraformaldehyde, washed with PBS, and incubated with Endothelin 1 monoclonal antibody (Product # MA3-005) at a dilution of 0.5 µg/test for 60 min at room temperature. Cells were then blocked in a solution of 2% BSA-PBS for 30 min at room temperature, incubated for 40 min at room temperature in the dark using a Dylight 488-conjugated goat anti-mouse IgG (H+L) secondary antibody, and re-suspended in PBS for FACS analysis.

Experimental details: FIGURE 5. A, Postoperative evolution of serum ET-1, a marker of endothelial-cell stress and hypoxia. Here, data are expressed as the mean and the standard error of the mean as whiskers, whereas they are expressed as the median and the 25&percnt to 75&percnt interquartile range in the text.&ast P < 0.05 for both SFS and S12 versus S6. B, ET-1 immunostaining of postreperfusion tissue samples. ET-1 expression was significantly upregulated in both the SFS and S12 groups, though the hepatocyte cords remained intact in the latter. S6 grafts, on the other hand, were notable for very minimal ET-1 staining of the endothelial lining.
